Gene: Kcnj12 (potassium inwardly-rectifying channel, subfamily J, member 12) Mus musculus
Symbol: Kcnj12
Name: potassium inwardly-rectifying channel, subfamily J, member 12
Description: Predicted to have PDZ domain binding activity and inward rectifier potassium channel activity. Predicted to be involved in potassium ion import across plasma membrane; protein homotetramerization; and regulation of ion transmembrane transport. Predicted to localize to several cellular components, including T-tubule; dendrite; and neuronal cell body. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; integumental system; and limb segment. Orthologous to several human genes including KCNJ12 (potassium inwardly rectifying channel subfamily J member 12); PARTICIPATES IN neuron-to-neuron signaling pathway via the chemical synapse; INTERACTS WITH 4,4'-diaminodiphenylmethane; 4,4'-sulfonyldiphenol; all-trans-retinoic acid.
Type: protein-coding
RefSeq Status: VALIDATED
Also known as: ATP-sensitive inward rectifier potassium channel 12; inward rectifier K(+) channel Kir2.2; IRK-2; IRK2; Kir2.2; MB-IRK2; MGC144838; MGC144839; potassium channel, inwardly rectifying subfamily J member 12
