K homology (KH) RNA-binding domain, type I; KH binds single-stranded RNA or DNA. It is found in a wide variety of proteins including ribosomal proteins, transcription factors and post-transcriptional modifiers of mRNA. There are two different KH domains that belong to different protein folds, but they share a single KH motif. The KH motif is folded into a beta alpha alpha beta unit. In addition to the core, type II KH domains (e.g. ribosomal protein S3) include an N-terminal extension and type I KH domains (e.g. hnRNP K) contain a C-terminal extension. Some KH-I superfamily members contain a divergent KH domain that lacks the RNA-binding GXXG motif. Some others have a mutated GXXG motif which may or may not have nucleic acid binding ability.

FUBP1, also called FBP, or FUSE-binding protein 1, or DNA helicase V, or DH V, binds RNA and single-stranded DNA (ssDNA) and may act both as activator and repressor of transcription. It regulates MYC expression by binding to a single-stranded far-upstream element (FUSE) upstream of the MYC promoter. FUBP2, also called FUSE-binding protein 2, or KH type-splicing regulatory protein (KSRP), or p75, is a single-strand nucleic acid binding protein implicated in a variety of cellular processes, including splicing in the nucleus, mRNA decay, maturation of miRNA, and transcriptional control of proto-oncogenes such as c-myc. It regulates the stability and/or translatability of many mRNA species, encoding immune-relevant proteins, either by binding to AU-rich elements (AREs) of mRNA 3'UTR or by facilitating miRNA biogenesis to target mRNA. FUBP3, also called FUSE-binding protein 3, or MARTA2, was previously shown to mediate dendritic targeting of MAP2 mRNA in neurons. It may interact with single-stranded DNA from the far-upstream element (FUSE) and activate gene expression. It is required for beta-actin mRNA localization. It also interacts with fibroblast growth factor 9 (FGF9) 3'-UTR UG repeats and positively controls FGF9 expression through increasing translation of FGF9 mRNA. FUBP proteins contain four K-homology (KH) RNA-binding domains. The model corresponds to the fourth one.

FUBP1, also called FBP, or FUSE-binding protein 1, or DNA helicase V, or DH V, binds RNA and single-stranded DNA (ssDNA) and may act both as activator and repressor of transcription. It regulates MYC expression by binding to a single-stranded far-upstream element (FUSE) upstream of the MYC promoter. FUBP2, also called FUSE-binding protein 2, or KH type-splicing regulatory protein (KSRP), or p75, is a single-strand nucleic acid binding protein implicated in a variety of cellular processes, including splicing in the nucleus, mRNA decay, maturation of miRNA, and transcriptional control of proto-oncogenes such as c-myc. It regulates the stability and/or translatability of many mRNA species, encoding immune-relevant proteins, either by binding to AU-rich elements (AREs) of mRNA 3'UTR or by facilitating miRNA biogenesis to target mRNA. FUBP3, also called FUSE-binding protein 3, or MARTA2, was previously shown to mediate dendritic targeting of MAP2 mRNA in neurons. It may interact with single-stranded DNA from the far-upstream element (FUSE) and activate gene expression. It is required for beta-actin mRNA localization. It also interacts with fibroblast growth factor 9 (FGF9) 3'-UTR UG repeats and positively controls FGF9 expression through increasing translation of FGF9 mRNA. FUBP proteins contain four K-homology (KH) RNA-binding domains. The model corresponds to the first one.

They are single-stranded nucleic acid binding proteins that bind preferentially to oligo dC. They act as iron chaperones for ferritin. In case of infection by poliovirus, PCBP1 plays a role in initiation of viral RNA replication in concert with the viral protein 3CD. PCBP2 is a major cellular poly(rC)-binding protein. It also binds poly(rU). PCBP2 negatively regulates cellular antiviral responses mediated by MAVS signaling. It acts as an adapter between MAVS and the E3 ubiquitin ligase ITCH, therefore triggering MAVS ubiquitination and degradation. PCBP2 forms a metabolon with the heme oxygenase 1/cytochrome P450 reductase complex for heme catabolism and iron transfer. Both PCBP1 and PCBP2 contain three K-homology (KH) RNA-binding domains. The model corresponds to the third one.

type I K homology (KH) RNA-binding domain found in Mask family proteins; The Mask family includes Drosophila melanogaster ankyrin repeat and KH domain-containing protein Mask, and its mammalian homologues Mask1/ANKHD1 and Mask2/ANKRD17. Mask, also called multiple ankyrin repeat single KH domain-containing protein, is a large ankyrin repeat and KH domain-containing protein involved in Drosophila receptor tyrosine kinase signaling. It acts as a mediator of receptor tyrosine kinase (RTK) signaling and may act either downstream of MAPK or transduce signaling through a parallel branch of the RTK pathway. Mask is required for the development and organization of indirect flight muscle sarcomeres by regulating the formation of M line and H zone and the correct assembly of thick and thin filaments in the sarcomere. Mask1/ANKHD1, also called HIV-1 Vpr-binding ankyrin repeat protein, or multiple ankyrin repeats single KH domain, or Hmask, is highly expressed in various cancer tissues and is involved in cancer progression, including proliferation and invasion. Mask2/ANKRD17, also called ankyrin repeat protein 17, or gene trap ankyrin repeat protein (GTAR), or serologically defined breast cancer antigen NY-BR-16, is a ubiquitously expressed ankyrin factor essential for the vascular integrity during embryogenesis. It may be directly involved in the DNA replication process and play pivotal roles in cell cycle and DNA regulation. It is also involved in innate immune defense against bacteria and viruses.

They are mainly involved in various posttranscriptional regulations, including mRNA stabilization or translational activation/silencing. Besides, PCBPs may share iron chaperone activity. PCBPs contain three K-homology (KH) RNA-binding domains. The model corresponds to the second one.

type I K homology (KH) RNA-binding domain found in Mask family proteins; The Mask family includes Drosophila melanogaster ankyrin repeat and KH domain-containing protein Mask, and its mammalian homologues Mask1/ANKHD1 and Mask2/ANKRD17. Mask, also called multiple ankyrin repeat single KH domain-containing protein, is a large ankyrin repeat and KH domain-containing protein involved in Drosophila receptor tyrosine kinase signaling. It acts as a mediator of receptor tyrosine kinase (RTK) signaling and may act either downstream of MAPK or transduce signaling through a parallel branch of the RTK pathway. Mask is required for the development and organization of indirect flight muscle sarcomeres by regulating the formation of M line and H zone and the correct assembly of thick and thin filaments in the sarcomere. Mask1/ANKHD1, also called HIV-1 Vpr-binding ankyrin repeat protein, or multiple ankyrin repeats single KH domain, or Hmask, is highly expressed in various cancer tissues and is involved in cancer progression, including proliferation and invasion. Mask2/ANKRD17, also called ankyrin repeat protein 17, or gene trap ankyrin repeat protein (GTAR), or serologically defined breast cancer antigen NY-BR-16, is a ubiquitously expressed ankyrin factor essential for the vascular integrity during embryogenesis. It may be directly involved in the DNA replication process and play pivotal roles in cell cycle and DNA regulation. It is also involved in innate immune defense against bacteria and viruses.

third type I K homology (KH) RNA-binding domain found in the family of neuro-oncological ventral antigen (Nova); The family includes two related neuronal RNA-binding proteins, Nova-1 and Nova-2. Nova-1, also called onconeural ventral antigen 1, or paraneoplastic Ri antigen, or ventral neuron-specific protein 1, may regulate RNA splicing or metabolism in a specific subset of developing neurons. It interacts with RNA containing repeats of the YCAY sequence. It is a brain-enriched splicing factor regulating neuronal alternative splicing. Nova-1 is involved in neurological disorders and carcinogenesis. Nova-2, also called astrocytic NOVA1-like RNA-binding protein, is a neuronal RNA-binding protein expressed in a broader central nervous system (CNS) distribution than Nova-1. It functions in neuronal RNA metabolism. NOVA family proteins contain three K-homology (KH) RNA-binding domains. The model corresponds to the third one.
