Summary: Predicted to enable actin filament binding activity. Acts upstream of or within cardiac myofibril assembly; negative regulation of actin filament polymerization; and sarcomere organization. Predicted to be located in striated muscle thin filament. Predicted to be active in cytoplasm and cytoskeleton. Is expressed in several structures, including central nervous system; genitourinary system; gut; heart; and musculoskeletal system.

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.
