About KCNJ12

Cytogenetic location: 17p11.2 Genomic coordinates (GRCh38): 17:21,376,357-21,419,870 (from NCBI)

This gene has 2 transcripts (splice variants), 251 orthologues and 15 paralogues. Broad expression in heart (RPKM 2.3), brain (RPKM 1.4) and 20 other tissues.

Summary

This gene encodes an inwardly rectifying K+ channel which may be blocked by divalent cations. This protein is thought to be one of multiple inwardly rectifying channels which contribute to the cardiac inward rectifier current (IK1). The gene is located within the Smith-Magenis syndrome region on chromosome 17. [provided by RefSeq, Jul 2008]
