    Summary
    Predicted to enable actin binding activity. Acts upstream of or within negative regulation of systemic arterial blood pressure and positive regulation of cardiac muscle contraction. Predicted to be located in cytoplasm and cytoskeleton. Is expressed in alimentary system; bladder wall; limb; and musculature. Orthologous to human SMTN (smoothelin).

    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.
