Scn5a - sodium voltage-gated channel alpha subunit 5

Enables ankyrin binding activity; fibroblast growth factor binding activity; and voltage-gated sodium channel activity involved in cardiac muscle cell action potential. Involved in several processes, including animal organ development; response to denervation involved in regulation of muscle adaptation; and sodium ion import across plasma membrane. Located in T-tubule and intercalated disc. Biomarker of brain ischemia and congestive heart failure. Human ortholog(s) of this gene implicated in heart conduction disease (multiple); intrinsic cardiomyopathy (multiple); and sudden infant death syndrome. Orthologous to human SCN5A (sodium voltage-gated channel alpha subunit 5). [provided by Alliance of Genome Resources, Apr 2022]
