Gene Gene information from NCBI Gene database.
Entrez ID 3760
Gene name Potassium inwardly rectifying channel subfamily J member 3
Gene symbol KCNJ3
Synonyms (NCBI Gene)
GIRK1KGAKIR3.1
Chromosome 2
Chromosome location 2q24.1
Summary Potassium channels are present in most mammalian cells, where they participate in a wide range of physiologic responses. The protein encoded by this gene is an integral membrane protein and inward-rectifier type potassium channel. The encoded protein, whi

Protein name G protein-activated inward rectifier potassium channel 1 (GIRK-1) (Inward rectifier K(+) channel Kir3.1) (Potassium channel, inwardly rectifying subfamily J member 3)
Protein function Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potass
