Summary: Enables actin filament binding activity. Involved in cardiac muscle contraction; positive regulation of heart rate by epinephrine; and ventricular cardiac muscle tissue morphogenesis. Acts upstream of or within in utero embryonic development. Located in myofibril. Is expressed in several structures, including central nervous system; gut; heart; limb segment; and musculature. Used to study dilated cardiomyopathy 1Y and hypertrophic cardiomyopathy 3.

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.
