| Tissue Specificity | Expressed in the epididymis (at protein level). Expressed in the kidney (at protein level). |
| Post Translational Modifications | ISGylated. Oxidation of Met-44 and Met-47 by MICALs (MICAL1, MICAL2 or MICAL3) to form methionine sulfoxide promotes actin filament depolymerization. MICAL1 and MICAL2 produce the (R)-S-oxide form. The (R)-S-oxide form is reverted by MSRB1 and MSRB2, which promote actin repolymerization. Monomethylation at Lys-84 (K84me1) regulates actin-myosin interaction and actomyosin-dependent processes. Demethylation by ALKBH4 is required for maintaining actomyosin dynamics supporting normal cleavage furrow ingression during cytokinesis and cell migration. Methylated at His-73 by SETD3. Methylation at His-73 is required for smooth muscle contraction of the laboring uterus during delivery. Actin, cytoplasmic 1: N-terminal cleavage of acetylated methionine of immature cytoplasmic actin by ACTMAP. Actin, cytoplasmic 1, N-terminally processed: N-terminal acetylation by NAA80 affects actin filament depolymerization and elongation, including elongation driven by formins. In contrast, filament nucleation by the Arp2/3 complex is not affected. |
| Function | Actin is a highly conserved protein that polymerizes to produce filaments that form cross-linked networks in the cytoplasm of cells. Actin exists in both monomeric (G-actin) and polymeric (F-actin) forms, both forms playing key functions, such as cell motility and contraction. In addition to their role in the cytoplasmic cytoskeleton, G- and F-actin also localize in the nucleus, and regulate gene transcription and motility and repair of damaged DNA. Part of the ACTR1A/ACTB filament around which the dynactin complex is built. The dynactin multiprotein complex activates the molecular motor dynein for ultra-processive transport along microtubules. |
