SCN4B - sodium voltage-gated channel beta subunit 4 Gene

Homo sapiens

Also known as LQT10; ATFB17; Navbeta4

Gene ID: 6330 | Gene type: protein coding

About SCN4B

Cytogenetic location: 11q23.3 Genomic coordinates (GRCh38): 11:118,133,377-118,152,823 (from NCBI)

This gene has 6 transcripts (splice variants), 263 orthologues, 6 paralogues and is associated with 3 phenotypes. Broad expression in fat (RPKM 19.5), brain (RPKM 8.6) and 18 other tissues.

Summary

The protein encoded by this gene is one of several Sodium Channel beta subunits. These subunits interact with voltage-gated alpha subunits to change Sodium Channel kinetics. The encoded transmembrane protein forms interchain disulfide bonds with SCN2A. Defects in this gene are a cause of long QT syndrome type 10 (LQT10). Three protein-coding and one non-coding transcript variant have been found for this gene.[provided by RefSeq, Mar 2009]
