G protein-activated inward rectifier potassium channel 2 is a protein that in humans is encoded by the KCNJ6 gene.[5][6][7] Mutation in KCNJ6 gene has been proposed to be the cause of Keppen-Lubinsky Syndrome (KPLBS). [8]

Function

[edit]

Potassium channels are present in most mammalian cells, where they participate in a wide range of physiologic responses. The protein encoded by this gene is an integral membrane protein and inward-rectifier type potassium channel. The encoded protein, which has a greater tendency to allow potassium to flow into a cell rather than out of a cell, is controlled by G-proteins and may be involved in the regulation of insulin secretion by glucose. It associates with two other G-protein-activated potassium channels to form a heteromultimeric pore-forming complex.[7]

Interactions

[edit]

KCNJ6 has been shown to interact with KCNJ9[9][10] and DLG1.[11]
