Biological Activity
The gene KCNK1 (potassium two pore domain channel subfamily K member 1) is a double-pore potassium channel th at functions in maintaining the renal potassium homeostasis. KCNK channel proteins are involved in cell volume, apoptosis, and proliferation. Alterations in these proteins have been associated with various diseases. Decreased levels of KCNK1 in human cardiac atria have been implicated in chronic atrial fibrillation. It functions as a suppressor of anchorage-independent growth in fibroblast.
