• Product name

    Anti-gamma Actin antibody [2A3]
    See all gamma Actin primary antibodies
  • Description

    Mouse monoclonal [2A3] to gamma Actin
  • Host species

  • Specificity

    This antibody does not cross react with other actin isoforms. The epitope recognized by ab123034 is highly conserved and the antibody is therefore expected to react with many other species.

    This antibody is highly specific for gamma-cytoplasmic actin (γ-actin 1; encoded by ACTG1). It does not cross-react with the gamma-actin isoform expressed in the enteric smooth muscle tissues (γ-actin 2; encoded by ACTG2).

  • Tested applications

  • Function

    Actins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells.
  • Involvement in disease

    Defects in ACTG1 are the cause of deafness autosomal dominant type 20 (DFNA20) [MIM:604717]; also called autosomal dominant deafness type 26 (DFNA26). DFNA20 is a form of sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information.
  • Sequence similarities

    Belongs to the actin family.
  • Post-translational

    The methylhistidine determined by Bienvenut et al is assumed to be the tele-methylhistidine isomer by similarity to the mouse ortholog.
  • Cellular localization

    Cytoplasm > cytoskeleton.
