Summary
Predicted to enable ATP binding activity; hydrolase activity; and protein kinase binding activity. Involved in several processes, including cellular response to potassium ion; response to steroid hormone; and skeletal muscle fiber adaptation. Predicted to be located in several cellular components, including filopodium; lamellipodium; and sarcomere. Predicted to be part of protein-containing complex. Predicted to be active in actin filament; stress fiber; and striated muscle thin filament. Human ortholog(s) of this gene implicated in congenital myopathy 2B; congenital myopathy 2C; and nemaline myopathy 3. Orthologous to human ACTA1 (actin alpha 1, skeletal muscle).

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.
