ATP-sensitive inward rectifier potassium channel 12 is a protein that in humans is encoded by the KCNJ12 gene.[1][2][3][4]


This gene encodes an inwardly rectifying K+ channel that may be blocked by divalent cations. This protein is thought to be one of multiple inwardly rectifying channels that contribute to the cardiac inward rectifier current (IK1). The gene is located within the Smith-Magenis syndrome region on chromosome 17.[4]


KCNJ12 has been shown to interact with LIN7C,[5][6] DLG4,[5][6] LIN7B,[5][6] DLG2,[5] DLG3,[5] DLG1,[5][6][7] APBA1,[5][6] LIN7A[5][6] and CASK.[5][6]
