    Summary
    Predicted to be a structural constituent of cytoskeleton. Involved in several processes, including positive regulation of cell adhesion; positive regulation of keratinocyte migration; and wound healing. Acts upstream of or within actomyosin structure organization. Located in apical part of cell; cytosol; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

    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.
