Also known as
Predicted to enable actin filament binding activity; calcium ion binding activity; and calcium-dependent protein binding activity. Predicted to contribute to actin binding activity. Predicted to be involved in regulation of muscle contraction and skeletal muscle contraction. Predicted to be part of troponin complex. Is expressed in several structures, including alimentary system; limb segment; skeletal musculature; urinary system; and urogenital ridge. Orthologous to human TNNC2 (troponin C2, fast skeletal type). [provided by Alliance of Genome Resources, Apr 2022]

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.
