ATP-sensitive inward rectifier K+ channel 14; K+ channel, inwardly rectifying subfamily J member 14; inward rectifier K+ channel Kir2.4; IRK4 (KCNJ14)

Function

• inwardly-rectifying K+ channel
• voltage dependence regulated by extracellular K+
• inward rectification due to blockage of outward current by internal Mg+2.
• low-conductance channel
• low affinity to channel blockers Ba+2 & Ce+2

Compartment

membrane

Expression

expressed preferentially in retina

More general terms

• inwardly-rectifying K+ channel subfamily J
