Summary: Enables muscle alpha-actinin binding activity and protein kinase C binding activity. Acts upstream of or within sarcomere organization. Located in Z disc. Is expressed in several structures, including central nervous system; heart; lower urinary tract; musculature; and sensory organ. Used to study congenital myopathy; dilated cardiomyopathy 1C; and myofibrillar myopathy 1. Human ortholog(s) of this gene implicated in dilated cardiomyopathy; dilated cardiomyopathy 1C; distal myopathy; and myofibrillar myopathy 4. Orthologous to human LDB3 (LIM domain binding 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.
