Protein Kinases, catalytic domain; The protein kinase superfamily is mainly composed of the catalytic domains of serine/threonine-specific and tyrosine-specific protein kinases. It also includes RIO kinases, which are atypical serine protein kinases, aminoglycoside phosphotransferases, and choline kinases. These proteins catalyze the transfer of the gamma-phosphoryl group from ATP to hydroxyl groups in specific substrates such as serine, threonine, or tyrosine residues of proteins.

26-206 9.35e-111

Catalytic domain of the Serine/Threonine protein kinase, Vaccinia Related Kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. VRKs were initially discovered due to its similarity to vaccinia virus B1R STK, which is important for viral replication. Vertebrates contain three VRK proteins. Human VRK1 is implicated in the regulation of many cellular processes including cell cycle progression and proliferation, stress responses, nuclear envelope assembly and chromatin condensation. It regulates cell cycle progression during the DNA replication period by inducing cyclin D1 expression. VRK1 also phosphorylates and regulates some transcription factors including p53, c-Jun, ATF2, and nuclear factor BAF. VRK1 stabilizes p53 by interfering with its mdm2-mediated degradation. Accumulation of p53, which blocks cell growth and division, is modulated by an autoregulatory loop between p53 and VRK1 (accumulated p53 downregulates VRK1). This autoregulatory loop has been found to be nonfunctional in some lung carcinomas. The VRK1 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

VRKs were initially discovered due to its similarity to vaccinia virus B1R STK, which is important for viral replication. They play important roles in cell signaling, nuclear envelope dynamics, apoptosis, and stress responses. Vertebrates contain three VRK proteins (VRK1, VRK2, and VRK3) while invertebrates, specifically fruit flies and nematodes, seem to carry only a single ortholog. Mutations of VRK in Drosophila and Caenorhabditis elegans showed varying phenotypes ranging from embryonic lethality to mitotic and meiotic defects resulting in sterility. In vertebrates, VRK1 is implicated in cell cycle progression and proliferation, nuclear envelope assembly, and chromatin condensation. VRK2 is involved in modulating JNK signaling. VRK3 is an inactive pseudokinase that inhibits ERK signaling. The VRK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

26-205 3.35e-58

Catalytic domain of the Serine/Threonine protein kinase, Vaccinia Related Kinase 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. VRKs were initially discovered due to its similarity to vaccinia virus B1R STK, which is important for viral replication. They play important roles in cell signaling, nuclear envelope dynamics, apoptosis, and stress responses. Vertebrates contain three VRK proteins. VRK2 exists as two alternative splice forms, A and B, which differ in their C-terminal regions. VRK2A, the predominant isoform, contains a hydrophobic tail and is anchored to the ER and mitochondria. It is expressed in all cell types. VRK2B lacks a membrane-anchor tail and is detected in the cytosol and the nucleus. Like VRK1, it can stabilize p53. VRK2B functionally replaces VRK1 in the nucleus of cell types where VRK1 is absent. VRK2 modulates hypoxia-induced stress responses by interacting with TAK1, an atypical MAPK kinase kinase which triggers cascades that activate JNK following oxidative stress. VRK2 also interacts with JIP1, a scaffold protein that assembles three consecutive members of a MAPK pathway. This interaction prevents the association of JNK with the signaling complex, leading to reduced phosphorylation and AP1-dependent transcription. The VRK2 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

73-208 7.75e-46

Pseudokinase domain of Vaccinia Related Kinase 3; The pseudokinase domain shows similarity to protein kinases but lacks crucial residues for catalytic activity. VRKs were initially discovered due to its similarity to vaccinia virus B1R STK, which is important for viral replication. They play important roles in cell signaling, nuclear envelope dynamics, apoptosis, and stress responses. Vertebrates contain three VRK proteins. VRK3 is an inactive pseudokinase that is unable to bind ATP. It achieves its regulatory function through protein-protein interactions. It negatively regulates ERK signaling by binding directly and enhancing the activity of the MAPK phosphatase VHR (vaccinia H1-related), which dephosphorylates and inactivates ERK. The VRK3 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine protein kinase, Casein Kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CK1 phosphorylates a variety of substrates including enzymes, transcription and splice factors, cytoskeletal proteins, viral oncogenes, receptors, and membrane-associated proteins. There are mutliple isoforms of CK1 and in mammals, seven isoforms (alpha, beta, gamma1-3, delta, and epsilon) have been characterized. These isoforms differ mainly in the length and structure of their C-terminal non-catalytic region. Some isoforms have several splice variants such as the long (L) and short (S) variants of CK1alpha. CK1 proteins are involved in the regulation of many cellular processes including membrane transport processes, circadian rhythm, cell division, apoptosis, and the development of cancer and neurodegenerative diseases. The CK1 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

CK1 phosphorylates a variety of substrates including enzymes, transcription and splice factors, cytoskeletal proteins, viral oncogenes, receptors, and membrane-associated proteins. There are mutliple isoforms of CK1 and in mammals, seven isoforms (alpha, beta, gamma1-3, delta, and epsilon) have been characterized. These isoforms differ mainly in the length and structure of their C-terminal non-catalytic region. This subfamily is composed of fungal CK1 homolog 1 proteins, also called Yck1 in Saccharomyces cerevisiae and Cki1 in Schizosaccharomyces pombe. Yck1 (or Yck1p) and Cki1 are plasma membrane-anchored proteins. Yck1 phosphorylates and regulates Khd1p, a RNA-binding protein that represses translation of bud-localized mRNA. Cki1 phosphorylates and regulates phosphatidylinositol (PI)-(4)P-5-kinase, which catalyzes the last step in the sythesis of PI(4,5)P2, which is involved in actin cytoskeleton remodeling and membrane traffic. The fungal CK1 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine protein kinase, Casein Kinase 1 gamma; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CK1 phosphorylates a variety of substrates including enzymes, transcription and splice factors, cytoskeletal proteins, viral oncogenes, receptors, and membrane-associated proteins. There are mutliple isoforms of CK1 and in mammals, seven isoforms (alpha, beta, gamma1-3, delta, and epsilon) have been characterized. These isoforms differ mainly in the length and structure of their C-terminal non-catalytic region. CK1gamma proteins are unique within the CK1 subfamily in that they are palmitoylated at the C-termini and are anchored to the plasma membrane. CK1gamma is involved in transducing the signaling of LDL-receptor-related protein 6 (LRP6) through direct phosphorylation following Wnt stimulation, resulting in the recruitment of the scaffold protein Axin. In Xenopus embryos, CK1gamma is required during anterio-posterior patterning. In higher vertebrates, three CK1gamma (gamma1-3) isoforms exist. In mammalian cells, CK1gamma2 has been implicated in regulating the synthesis of sphingomyelin, a phospholipid that is found in the outer leaflet of the plasma membrane, by hyperphosphorylating and inactivating the ceramide transfer protein CERT. CK1gamma2 also phosphorylates the transcription factor Smad-3 resulting in its ubiquitination and degradation. It inhibits Smad-3 mediated responses of Transforming Growth Factor-beta (TGF-beta) including cell growth arrest. The CK1 gamma subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

These isoforms differ mainly in the length and structure of their C-terminal non-catalytic region. The delta and epsilon isoforms of CK1 play important roles in circadian rhythm and cell growth. They phosphorylate PERIOD proteins (PER1-3), which are circadian clock proteins that fulfill negative regulatory functions. PER phosphorylation leads to its degradation. However, CRY proteins form a complex with PER and CK1delta/epsilon that protects PER from degradation and leads to nuclear accummulation of the complex, which inhibits BMAL1-CLOCK dependent transcription activation. CK1delta/epsilon also phosphorylate the tumor suppressor p53 and the cellular oncogene Mdm2, which are key regulators of cell growth, genome integrity, and the development of cancer. This subfamily also includes the CK1 fungal proteins Saccharomyces cerevisiae HRR25 and Schizosaccharomyces pombe HHP1. These fungal proteins are involved in DNA repair. The CK1 delta/epsilon subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine protein kinase, Tau-Tubulin Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. TTBK is a neuron-specific kinase that phosphorylates the microtubule-associated protein tau and promotes its aggregation. Higher vertebrates contain two TTBK proteins, TTBK1 and TTBK2, both of which have been implicated in neurodegeneration. TTBK1 has been linked to Alzheimer's disease (AD) while TTBK2 is associated with spinocerebellar ataxia type 11 (SCA11). Both AD and SCA11 patients show the presence of neurofibrillary tangles in the brain. The Drosophila TTBK homolog, Asator, is an essential protein that localizes to the mitotic spindle during mitosis and may be involved in regulating microtubule dynamics and function. The TTBK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.
