Inward rectifier K+ channel from human heart and brain: cloning and stable expression in a human cell line.


We have cloned the human homologue of the inward rectifier K+ channel from both heart and brain tissue (HHBIRK1). The human clones were identical to each other in their coding regions and were highly homologous to the mouse macrophage (IRK1) channel. The inward rectifier currents from human and mouse clones were characterized using a novel strategy for… (More)
