Histidine kinase-like ATPase domain of DNA mismatch repair proteins Escherichia coli MutL, human MutL homologs (MLH/ PMS), and related domains; This family includes the histidine kinase-like ATPase (HATPase) domains of Escherichia coli MutL, human MLH1 (mutL homolog 1), human PMS1 (PMS1 homolog 1, mismatch repair system component), human MLH3 (mutL homolog 3), and human PMS2 (PMS1 homolog 2, mismatch repair system component). MutL homologs (MLH/PMS) participate in MMR (DNA mismatch repair), and in addition have role(s) in DNA damage signaling and suppression of homologous recombination (recombination between partially homologous parental DNAs). The primary role of MutL in MMR is to mediate protein-protein interactions during mismatch recognition and strand removal; a ternary complex is formed between MutS, MutL, and the mismatched DNA, which activates the MutH endonuclease.

MutL_Trans_hPMS2_like: transducer domain, having a ribosomal S5 domain 2-like fold, found in proteins similar to human PSM2 (hPSM2). hPSM2 belongs to the DNA mismatch repair (MutL/MLH1/PMS2) family. This transducer domain is homologous to the second domain of the DNA gyrase B subunit, which is known to be important in nucleotide hydrolysis and the transduction of structural signals from ATP-binding site to the DNA breakage/reunion regions of the enzymes. Included in this group are proteins similar to yeast PMS1. The yeast MLH1-PMS1 and the human MLH1-PMS2 heterodimers play a role in meiosis. hMLH1-hPMS2 also participates in the repair of all DNA mismatch repair (MMR) substrates. Cells lacking hPMS2 have a strong mutator phenotype and display microsatellite instability (MSI). Mutation in hPMS2 causes predisposition to HPNCC and Turcot syndrome.

MutL_Trans: transducer domain, having a ribosomal S5 domain 2-like fold, conserved in the C-terminal domain of DNA mismatch repair (MutL/MLH1/PMS2) family. This transducer domain is homologous to the second domain of the DNA gyrase B subunit, which is known to be important in nucleotide hydrolysis and the transduction of structural signals from ATP-binding site to the DNA breakage/reunion regions of the enzymes. Included in this group are proteins similar to human MLH1, hPMS2, hPMS1, hMLH3 and E. coli MutL, MLH1 forms heterodimers with PMS2, PMS1 and MLH3. These three complexes have distinct functions in meiosis. hMLH1-hPMS2 also participates in the repair of all DNA mismatch repair (MMR) substrates. Roles for hMLH1-hPMS1 or hMLH1-hMLH3 in MMR have not been established. Cells lacking either hMLH1 or hPMS2 have a strong mutator phenotype and display microsatellite instability (MSI). Mutation in hMLH1 causes predisposition to HNPCC, Muir-Torre syndrome and Turcot syndrome (HNPCC variant). Mutation in hPMS2 causes predisposition to HPNCC and Turcot syndrome. Mutation in hMLH1 accounts for a large fraction of HNPCC families. There is no convincing evidence to support hPMS1 having a role in HNPCC predisposition. It has been suggested that hMLH3 may be a low risk gene for colorectal cancer; however there is little evidence to support it having a role in classical HNPCC. It has been suggested that during initiation of DNA mismatch repair in E. coli, the mismatch recognition protein MutS recruits MutL in the presence of ATP. The MutS(ATP)-MutL ternary complex formed, then recruits the latent endonuclease MutH.

MutL_Trans: transducer domain, having a ribosomal S5 domain 2-like fold, conserved in the C-terminal domain of type II DNA topoisomerases (Topo II) and DNA mismatch repair (MutL/MLH1/PMS2) proteins. This transducer domain is homologous to the second domain of the DNA gyrase B subunit, which is known to be important in nucleotide hydrolysis and the transduction of structural signals from ATP-binding site to the DNA breakage/reunion regions of the enzymes. The GyrB dimerizes in response to ATP binding, and is homologous to the N-terminal half of eukaryotic Topo II and the ATPase fragment of MutL. Type II DNA topoisomerases catalyze the ATP-dependent transport of one DNA duplex through another, in the process generating transient double strand breaks via covalent attachments to both DNA strands at the 5' positions. Included in this group are proteins similar to human MLH1 and PMS2. MLH1 forms a heterodimer with PMS2 which functions in meiosis and in DNA mismatch repair (MMR). Cells lacking either hMLH1 or hPMS2 have a strong mutator phenotype and display microsatellite instability (MSI). Mutation in hMLH1 accounts for a large fraction of Lynch syndrome (HNPCC) families.

Histidine kinase-like ATPase domain of two-component sensor histidine kinases similar to Escherichia coli K-12 DpiB, DcuS, and Bacillus subtilis CitS, DctS, and YufL; This family includes histidine kinase-like ATPase domains of Escherichia coli K-12 DpiB and DcuS, and Bacillus subtilis CitS, DctS and MalK histidine kinases (HKs) all of which are two component transduction systems (TCSs). E. coli K-12 DpiB (also known as CitA) is the histidine kinase (HK) of DpiA-DpiB, a two-component signal transduction system (TCS) required for the expression of citrate-specific fermentation genes and genes involved in plasmid inheritance. E. coli K-12 DcuS (also known as YjdH) is the HK of DcuS-DcuR, a TCS that in the presence of the extracellular C4-dicarboxlates, activates the expression of the genes of anaerobic fumarate respiration and of aerobic C4-dicarboxylate uptake. CitS is the HK of Bacillus subtilis CitS-CitT, a TCS which regulates expression of CitM, the Mg-citrate transporter. Bacillus subtilis DctS forms a tripartite sensor unit (DctS/DctA/DctB) for sensing C4 dicarboxylates. Bacillus subtilis MalK (also known as YfuL) is the HK of MalK-MalR (YufL-YufM) a TCS which regulates the expression of the malate transporters MaeN (YufR) and YflS, and is essential for utilization of malate in minimal medium. Proteins having this DpiB-CitA-like HATPase domain generally have sensor domains such as Cache and PAS, and a histidine kinase A (HisKA)-like SpoOB-type, alpha-helical domain.

Histidine kinase-like ATPase domain of type IIB topoisomerase, Topo VI, subunit B; This family includes the histidine kinase-like ATPase (HATPase) domain of the B subunit of topoisomerase VI (Topo VIB). Topo VI is a heterotetrameric complex composed of two TopVIA and two TopVIB subunits and is categorized as a type II B DNA topoisomerase. It is found in archaea and also in plants. Type II enzymes cleave both strands of a DNA duplex and pass a second duplex through the resulting break in an ATP-dependent mechanism. DNA cleavage by Topo VI generates two-nucleotide 5'-protruding ends.

Histidine kinase-like ATPase domain of human microrchidia (MORC) family CW-type zinc finger proteins MORC1-4, and related domains; This family includes the histidine kinase-like ATPase (HATPase) domain of human microrchidia (MORC) family CW-type zinc finger proteins MORC1-4, and related domains. In addition to the HATPase domain, MORC family proteins have a CW-type zinc finger domain containing four conserved cysteines and two conserved tryptophans, and coiled-coil domains at the carboxy-terminus. MORC1 has cross-species differential methylation in association with early life stress, and genome-wide association with major depressive disorder (MDD). MORC2 is involved in several nuclear processes, including transcription modulation and DNA damage repair, and exhibits a cytosolic function in lipogenesis, adipogenic differentiation, and lipid homeostasis by increasing the activity of ACLY. MORC3 regulates p53, and is an antiviral factor which plays an important role during HSV-1 and HCMV infection, and is a positive regulator of influenza virus transcription. MORC4 is highly expressed in a subset of diffuse large B-cell lymphomas and has potential as a lymphoma biomarker.
