Rabbit anti-Human KCNJ9 Polyclonal Antibody

Uniprot Id

Q92806

Target Species

Human

Target Name

KCNJ9

Target Full Name

G protein-activated inward rectifier potassium channel 3

Target Function

This receptor is controlled by G proteins. 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 potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium.

Target Subcellular Location

Membrane; Multi-pass membrane protein.

Target Protein Families

Inward rectifier-type potassium channel (TC 1.A.2.1) family, KCNJ9 subfamily

Target Synonyms

KCNJ9; GIRK3; G protein-activated inward rectifier potassium channel 3; GIRK-3; Inward rectifier K(+ channel Kir3.3; Potassium channel, inwardly rectifying subfamily J member 9

Target Background

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, which has a greater tendency to allow potassium to flow into a cell rather than out of a cell, is controlled by G-proteins. It associates with another G-protein-activated potassium channel to form a heteromultimeric pore-forming complex.
