Description

potassium inwardly-rectifying channel, subfamily J, member 3

Gene Summary

Contributes to G-protein activated inward rectifier potassium channel activity. Predicted to be involved in potassium ion import across plasma membrane and regulation of monoatomic ion transmembrane transport. Part of inward rectifier potassium channel complex. Is active in parallel fiber to Purkinje cell synapse and presynaptic membrane. Is expressed in several structures, including adrenal gland; alimentary system; brain; male reproductive gland or organ; and thymus. Orthologous to human KCNJ3 (potassium inwardly rectifying channel subfamily J member 3). [provided by Alliance of Genome Resources, Jul 2025]
