Gene: KCNA5 (potassium voltage-gated channel subfamily A member 5) Homo sapiens
Symbol: KCNA5
Name: potassium voltage-gated channel subfamily A member 5
CRRD ID: 731065
Description: Exhibits several functions, including alpha-actinin binding activity; scaffold protein binding activity; and voltage-gated potassium channel activity. Involved in several processes, including cardiac conduction; membrane hyperpolarization; and regulation of ion transport. Localizes to several cellular components, including intercalated disc; membrane raft; and voltage-gated potassium channel complex. Predicted to colocalize with caveola. Implicated in familial atrial fibrillation and pulmonary hypertension. Biomarker of pulmonary hypertension and stomach cancer.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: ATFB7; cardiac potassium channel; HCK1; HK2; HPCN1; insulinoma and islet potassium channel; KV1.5; MGC117058; MGC117059; PCN1; potassium channel 1; potassium channel protein; potassium channel, voltage gated shaker related subfamily A, member 5; potassium voltage-gated channel, shaker-related subfamily, member 5; voltage-gated potassium channel HK2; voltage-gated potassium channel protein Kv1.5; voltage-gated potassium channel subunit Kv1.5
