Summary: Predicted to enable actin filament binding activity. Acts upstream of or within eye development; heart development; and striated muscle cell development. Predicted to be active in several cellular components, including Z disc; cell junction; and cortical actin cytoskeleton. Is expressed in several structures, including brain; cardiovascular system; eye; muscle; and ovary. Human ortholog(s) of this gene implicated in arrhythmogenic right ventricular cardiomyopathy; congenital myopathy 8; and dilated cardiomyopathy 1AA. Orthologous to human ACTN2 (actinin alpha 2).

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.
