Recombinant Human Sodium channel protein type 3 subunit alpha (SCN3A), Truncated

Uniprot Id

Q9NY46

Target Species

Human

Target Name

SCN3A

Target Full Name

Sodium channel protein type 3 subunit alpha

Target Function

Mediates the voltage-dependent sodium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, forms a sodium-selective channel through which Na(+) ions may pass in accordance with their electrochemical gradient. May contribute to the regulation of serotonin/5-hydroxytryptamine release by enterochromaffin cells. In pancreatic endocrine cells, required for both glucagon and glucose-induced insulin secretion.

Target Subcellular Location

Cell membrane; Multi-pass membrane protein.

Target Protein Families

Sodium channel (TC 1.A.1.10) family, Nav1.3/SCN3A subfamily

Target Tissue Specificity

Expressed in enterochromaffin cells in both colon and small bowel (at protein level).

Target Background

Voltage-gated sodium channels are transmembrane glycoprotein complexes composed of a large alpha subunit with 24 transmembrane domains and one or more regulatory beta subunits. They are responsible for the generation and propagation of action potentials in neurons and muscle. This gene encodes one member of the sodium channel alpha subunit gene family, and is found in a cluster of five alpha subunit genes on chromosome 2. Multiple transcript variants encoding different isoforms have been found for this gene.
