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.

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 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 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.

nucleotide-binding domain (NBD) of actin, actin-related proteins T1-T3 (Arp-T1-3), and similar proteins; The family includes actin and human actin-related proteins T1, T2, and T3. Actin is a ubiquitous protein involved in the formation of filaments that are major components of the cytoskeleton. It is a highly dynamic structural protein network involved in processes such as cell contraction, cell motility, vesicle trafficking, intracellular organization, cytokinesis, endocytosis and apoptosis. Arp-T1, encoded by ACTRT1/ARPT1 gene expressed in testis, negatively regulates the Hedgehog (SHH) signaling, binds to the promoter of the SHH signaling mediator, GLI1, and inhibits its expression. Arp-T2 (also called actin-related protein M2; encoded by ACTRT2/ARPM2 gene expressed in testis and various other cell types) and Arp-T3 (also called actin-related protein M1; encoded by ACTRT3/ARPM1 gene expressed in all tested human tissues) play general roles in the organization of the cytoskeleton like other cytoplasmic actin-related proteins.

nucleotide-binding domain (NBD) of the actin-related protein 4 (Arp4)-like subfamily; The Arp4-like subfamily includes Arp4, also called actin-like protein 4, from fungi and plants. Saccharomyces cerevisiae Arp4 acts synergistically with Arp8 to depolymerize F-actin; it binds ATP, but unlike conventional actin, does not form filaments. It is a component of the NuA4 histone acetyltransferase complex, the chromatin-remodeling INO80 complex and the SWR1 chromatin remodeling complex. Arabidopsis thaliana Arp4 is involved in several developmental processes including organization of plant organs, flowering time, anther development, flower senescence and fertility, probably by regulating the chromatin structure. This family also includes human homologs of yeast and plant, which are actin-like protein 6A (encoded by the ACTL6A gene; also known as ArpNbeta, 53 kDa BRG1-associated factor A/BRG1-associated factor 53A/BAF35A, and INO80 complex subunit K/INO80K) and actin-like protein 6B (encoded by the ACTL6B gene; also known as ArpNalpha, 53 kDa BRG1-associated factor B/BRG1-associated factor 53B/BAF35B). ACTL6A and ACTL6B are involved in transcriptional activation and repression of select genes by chromatin remodeling (alteration of DNA-nucleosome topology). They are components of numerous complexes with chromatin remodeling and histone acetyltransferase activity. ACTL6A is also a putative core component of the chromatin remodeling INO80 complex which is involved in transcriptional regulation, DNA replication and probably DNA repair. Schizosaccharomyces pombe actin-related protein 42 (Arp42) is also included in this family. It is also a component of SWI/SNF and RSC complexes.

In mammalian, ACTL7A is expressed in a wide variety of adult tissues, while the ACTL7B is expressed in spermatids through the elongation phase of spermatid development. ACTL7A, also called actin-like-7-alpha, or T-ACTIN-2 in mouse, may play an important role in formation and fusion of Golgi-derived vesicles during acrosome biogenesis. ACTL7B, also called actin-like-7-beta, acts as a key regulator of spermiogenesis that is required for male fertility. ACTL9 is a testis-specific protein that plays an important role in fusion of proacrosomal vesicles and perinuclear theca formation.

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.
