Summaries for ACTG1 Gene

Entrez Gene Summary for ACTG1 Gene

  • Actins are highly conserved proteins that are involved in various types of cell motility, and maintenance of the cytoskeleton. In vertebrates, three main groups of actin isoforms, alpha, beta and gamma have been identified. The alpha actins are found in muscle tissues and are a major constituent of the contractile apparatus. The beta and gamma actins co-exist in most cell types as components of the cytoskeleton, and as mediators of internal cell motility. Actin, gamma 1, encoded by this gene, is a cytoplasmic actin found in non-muscle cells. Mutations in this gene are associated with DFNA20/26, a subtype of autosomal dominant non-syndromic sensorineural progressive hearing loss. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Jan 2011]

GeneCards Summary for ACTG1 Gene

ACTG1 (Actin Gamma 1) is a Protein Coding gene. Diseases associated with ACTG1 include baraitser-winter syndrome 2 and deafness, autosomal dominant 20/26. Among its related pathways are Ras signaling pathway and Proteoglycans in cancer. GO annotations related to this gene include identical protein binding and structural constituent of cytoskeleton. An important paralog of this gene is ACTB.

Tocris Summary for ACTG1 Gene

  • Actin is a ubiquitous globular protein that is one of the most highly-conserved proteins known. It is found in two main states; G-actin is the globular monomeric form, whereas F-actin forms helical polymers. Both G- and F-actin are intrinsically flexible structures - a feature vital in actin's role as a dynamic filament network. Actin has four major functions. Firstly, F-actin polymers form microfilaments - polar intracellular 'tracks' for kinesin motor proteins, allowing the transport of vesicles, organelles and other cargo. Actin is a component of the cytoskeleton and links to alpha-actinin, E-cadherin and beta-catenin at adherens junctions. This gives mechanical support to cells and attaches them to each other and the extracellular matrix. In muscle cells, actin-rich thin filaments associate with myosin-rich thick filaments to form actomyosin myofibrils. Using energy from the hydrolysis of ATP, myofibrils undergo cyclic shortening through actin-myosin head interactions, which represents the mechanics of muscle contraction. Finally, actin has a role in cell motility through polymerization and depolymerization of fibrils.

Post-translational modifications for ACTG1 Gene

  • 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
  • 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 (By similarity).
  • The methylhistidine determined by Bienvenut et al is assumed to be the tele-methylhistidine isomer by similarity to the mouse ortholog
  • Ubiquitination at Lys18, Lys50, Lys61, Lys84, Lys113, Lys191, Lys213, Lys215, Lys291, Lys315, Lys326, and Lys328
