Gene: KCNK9 (potassium two pore domain channel subfamily K member 9) Homo sapiens
Symbol: KCNK9
Name: potassium two pore domain channel subfamily K member 9
Description: Predicted to have potassium ion leak channel activity. Predicted to be involved in potassium ion transmembrane transport and stabilization of membrane potential. Predicted to localize to the integral component of plasma membrane. Implicated in Birk-Barel syndrome.
Type: protein-coding
RefSeq Status: REVIEWED
