nucleotide-binding domain (NBD) of the actin-related protein 8 (Arp8)-like subfamily; The Arp8-like family includes Arp8, also called actin-like protein 8, from vertebrates and fungi. Human Arp8 is encoded by the ACTR8 gene and is also known as INO80 complex subunit N. It plays an important role in the functional organization of mitotic chromosomes. Arp8 exhibits low basal ATPase activity, and is unable to polymerize. It is probably a core component of the chromatin remodeling INO80 complex which is involved in transcriptional regulation, DNA replication, and probably DNA repair. it is required for the recruitment of INO80 (and probably the INO80 complex) to sites of DNA damage. Arp8 strongly prefers nucleosomes and H3-H4 tetramers over H2A-H2B dimers, suggesting it may act as a nucleosome recognition module within the complex. This subfamily also contains Arabidopsis thaliana Arp9.

4.47e-20
nucleotide-binding domain (NBD) of actin and actin-related proteins (ARPs); Actin is ubiquitous in eukaryotes, and the major component of the actin cytoskeleton; monomeric globular protein (G-actin) reversibly polymerizes to form filaments (F-actin). Each actin protomer binds one molecule of ATP and either calcium or magnesium ions. F-actin filaments form with the consequent hydrolysis of ATP. Some actin-related proteins (Arps) have roles in cytoskeletal functions, such as actin polymerization (Arp2/3) and dynein motor activity (Arp1). Both conventional actin and specific Arps have been implicated in chromatin remodeling and/or transcription regulation. The actin/ARP family belongs to the ASKHA (Acetate and Sugar Kinases/Hsc70/Actin) superfamily, all members of which share a common characteristic five-stranded beta sheet occurring in both the N- and C-terminal domains.

nucleotide-binding domain (NBD) of Saccharomyces cerevisiae actin-related protein 9 (Arp9) and similar proteins; Saccharomyces cerevisiae Arp9, also called actin-like protein 9, chromatin structure-remodeling complex protein ARP9, or SWI/SNF complex component ARP9, is a component of the chromatin structure remodeling complex (RSC), which is involved in transcription regulation and nucleosome positioning. It is also part of the SWI/SNF complex, an ATP-dependent chromatin remodeling complex, which is required for the positive and negative regulation of gene expression of many genes. Arp9 forms a stable heterodimer with Arp7 protein in both the RSC and SWI/SNF chromatin-remodeling complexes. It has been suggested that this dimer functions as a module with DNA bending proteins, to achieve correct architecture and facilitate complex-complex interactions. Fission yeast SWI/SNF and RSC complexes do not contain Arp7 and Arp8, but instead contain Arp9 and Arp42.

5.86e-06
nucleotide-binding domain (NBD) of the actin-like protein MamK family; MamK, also called magnetosome cytoskeleton protein MamK, is a protein with ATPase activity which forms dynamic cytoplasmic filaments (probably with paralog MamK-like) that may organize magnetosomes into long chains running parallel to the long axis of the cell. Turnover of MamK filaments is probably promoted by MamK-like (e.g.. MamJ and/or LimJ), which provides a monomer pool. MamK forms twisted filaments in the presence of ATP or GTP. It serves to close gaps between magnetosomes in the chain. Interaction with MCP10 is involved in controlling the response to magnetic fields, possibly by controlling flagellar rotation. The MamK family belongs to the ASKHA (Acetate and Sugar Kinases/Hsc70/Actin) superfamily, all members of which share a common characteristic five-stranded beta sheet occurring in both the N- and C-terminal domains.

nucleotide-binding domain (NBD) of actin-related protein2 (Arp2) and similar proteins; Arp2, also called actin-like protein 2, is the ATP-binding component of the Arp2/3 complex, a multiprotein complex that mediates actin polymerization upon stimulation by nucleation-promoting factor (NPF). The Arp2/3 complex is comprised of 7 proteins (Arp2, Arp3, and five conserved proteins, ARPC1-5). It generates cytoplasmic branched filaments networks, by promoting nucleation of actin filaments as 70 degrees branches on the side of older filaments. It is activated, by simultaneously binding to a pre-existing filament and a nucleation promoting factor plus an actin monomer. Daughter branches subsequently detach/debranch from the mother filament. Its Arp2 and Arp3 subunits must be loaded with ATP for it to initiate the assembly of branched actin filaments. ATP hydrolysis may be required for branch initiation or debranching. The Arp2/3 complex is also found in the nucleus where it plays a role in promoting de novo actin polymerization and in RNA polymerase II-dependent transcription. This may in part be through regulating nuclear actin polymerization in a way like its function in the cytoplasm. Human Arp2 is encoded by the ACTR2 gene.

nucleotide-binding domain (NBD) of the plasmid segregation protein ParM-like domain family; ParM is a plasmid-encoded bacterial homolog of actin, which polymerizes into filaments similar to F-actin, and plays a vital role in plasmid segregation. ParM filaments segregate plasmids paired at midcell into the individual daughter cells. This subfamily also contains Thermoplasma acidophilum Ta0583, an active ATPase at physiological temperatures, which has a propensity to form filaments. ParM-like proteins belong to the ASKHA (Acetate and Sugar Kinases/Hsc70/Actin) superfamily of phosphotransferases, all members of which share a common characteristic five-stranded beta sheet occurring in both the N- and C-terminal domains.

nucleotide-binding domain (NBD) of the PilM-like domain family; The PilM-like family includes type IV pilus inner membrane component PilM, cell division protein FtsA, and ethanolamine utilization protein EutJ. PilM is an inner membrane component of the type IV (T4S) secretion system that plays a role in surface and host cell adhesion, colonization, biofilm maturation, virulence, and twitching, a form of surface-associated motility. FtsA is an essential cell division protein that assists in the assembly of the Z ring. It may serve as the principal membrane anchor for the Z ring. It is also required for the recruitment to the septal ring of the downstream cell division proteins FtsK, FtsQ, FtsL, FtsI and FtsN. EutJ may protect ethanolamine ammonia-lyase (EAL, eutB-eutC) from inhibition. It may also function in assembling the bacterial microcompartment and/or in refolding EAL, suggesting it may have chaperone activity. Members in PilM-like family belong to the ASKHA (Acetate and Sugar Kinases/Hsc70/Actin) superfamily of phosphotransferases, all members of which share a common characteristic five-stranded beta sheet occurring in both the N- and C-terminal domains.

nucleotide-binding domain (NBD) of the cell shape-determining proteins MreB, Mbl, MreBH and similar proteins; MreB proteins are bacterial actin homologs that may play a role in cell shape determination by positioning the cell wall synthetic machinery. MreB has also been implicated in chromosome segregation; specifically, MreB is thought to bind to and segregate the replication origin of bacterial chromosomes. The family includes three MreB isoforms, MreB (also called actin-like MreB protein or rod shape-determining protein MreB), Mbl (also called actin-like Mbl protein or rod shape-determining protein Mbl) and MreBH (also called actin-like MreBH protein or rod shape-determining protein MreBH), in cell morphogenesis of Bacillus subtilis. All isoforms can support rod-shaped cell growth normal conditions. They form membrane-associated dynamic filaments that are essential for cell shape determination. They act by regulating cell wall synthesis and cell elongation, and thus cell shape. The feedback loops between cell geometry and their localizations may maintain elongated cell shape by targeting cell wall growth to regions of negative cell wall curvature. Filaments rotate around the cell circumference in concert with the cell wall synthesis enzymes. The process is driven by the cell wall synthesis machinery and does not depend on their polymerization. They organize peptidoglycan synthesis in the lateral cell wall. MreB, Mbl and MreBH can form a complex. The MreB-like family belongs to the ASKHA (Acetate and Sugar Kinases/Hsc70/Actin) superfamily, all members of which share a common characteristic five-stranded beta sheet occurring in both the N- and C-terminal domains.
