GENE INFORMATION

Synonyms

Description

Potassium channel, inwardly rectifying subfamily J, member 12 (HGNC Symbol)

Entrez gene 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]
