Description

potassium inwardly-rectifying channel, subfamily J, member 3

Gene Summary

Enables G-protein activated inward rectifier potassium channel activity; phosphatidylinositol-4,5-bisphosphate binding activity; and voltage-gated monoatomic ion channel activity involved in regulation of presynaptic membrane potential. Contributes to inward rectifier potassium channel activity. Involved in response to electrical stimulus. Located in T-tubule and external side of plasma membrane. Orthologous to human KCNJ3 (potassium inwardly rectifying channel subfamily J member 3). [provided by Alliance of Genome Resources, Jun 2025]
