About KCNQ5

Cytogenetic location: 6q13 Genomic coordinates (GRCh38): 6:72,622,064-73,198,853 (from NCBI)

This gene has 14 transcripts (splice variants), 280 orthologues, 31 paralogues and is associated with 4 phenotypes. Biased expression in brain (RPKM 8.7), thyroid (RPKM 2.7) and 6 other tissues.

Summary

This gene is a member of the KCNQ Potassium Channel gene family that is differentially expressed in subregions of the brain and in skeletal muscle. The protein encoded by this gene yields currents that activate slowly with depolarization and can form heteromeric channels with the protein encoded by the KCNQ3 gene. Currents expressed from this protein have voltage dependences and inhibitor sensitivities in common with M-currents. They are also inhibited by M1 muscarinic receptor activation. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2009]
