About Kcnk2

Summary

Enables outward rectifier Potassium Channel activity; Potassium Channel Inhibitor activity; and potassium ion leak channel activity. Involved in several processes, including cochlea development; negative regulation of cardiac muscle cell proliferation; and positive regulation of cellular response to hypoxia. Located in several cellular components, including apical plasma membrane; astrocyte projection; and calyx of Held. Is integral component of plasma membrane. Used to study transient cerebral ischemia. Biomarker of brain ischemia; congestive heart failure; myocardial infarction; and transient cerebral ischemia. Orthologous to human KCNK2 (potassium two pore domain channel subfamily K member 2).
