About Scn3a

Chromosome 2: 65,287,462-65,397,971 reverse strand.GRCm39:CM000995.3

This gene has 8 transcripts (splice variants), 130 orthologues, 26 paralogues and is associated with 5 phenotypes. Biased expression in whole brain E14.5 (RPKM 13.5), CNS E18 (RPKM 13.4) and 6 other tissues.

Summary

Predicted to enable Calmodulin binding activity; sodium ion binding activity; and voltage-gated Sodium Channel activity. Predicted to be involved in several processes, including neuronal action potential; response to pyrethroid; and sodium ion transmembrane transport. Predicted to act upstream of or within regulation of ion transmembrane transport and sodium ion transport. Located in cytoplasm and membrane. Is expressed in cerebral cortex; heart; sciatic nerve; sympathetic ganglion; and telencephalon. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 62 and focal epilepsy. Orthologous to human SCN3A (sodium voltage-gated channel alpha subunit 3).
