The specific function of this gene has not yet been determined; however, the protein it encodes is known to be a major constituent of the ARP2/3 complex. This complex is located at the cell surface and is essential to cell shape and motility through lamellipodial actin assembly and protrusion. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
ACTR2 (Actin Related Protein 2) is a Protein Coding gene. Diseases associated with ACTR2 include Wiskott-Aldrich Syndrome and Myopathy, Centronuclear, 2. Among its related pathways are Association Between Physico-Chemical Features and Toxicity Associated Pathways and Development Slit-Robo signaling. Gene Ontology (GO) annotations related to this gene include actin filament binding and structural constituent of cytoskeleton. An important paralog of this gene is ACTC1.
