Summary
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. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Mar 2013]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

    See identical proteins and their annotated locations for NP_001264069.1

    Status: REVIEWED

    Description
    Transcript Variant: This variant (2) uses an alternate first exon compared to variant 1, resulting in translation initiation at a downstream AUG and an isoform (2) that is shorter at the N-terminus compared to isoform 1.

RNA

  1. NR_102318.1 RNA Sequence

    Status: REVIEWED

    Description
    Transcript Variant: This variant (3) lacks an alternate coding exon compared to variant 1, that causes a frameshift. This variant is represented as non-coding due to the presence of an upstream ORF that is predicted to interfere with translation of the longest ORF; translation of the upstream ORF renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
