Anti-KCNE3 Antibody

Potassium voltage-gated channel subfamily E member 3; MinK-related peptide 2; Minimum potassium ion channel-related peptide 2; Potassium channel subunit beta MiRP2; KCNE3;

Expressed in hippocampal neurons (at protein level) (PubMed:12954870) . Widely expressed with highest levels in kidney and moderate levels in small intestine.

Ancillary protein that assembles as a beta subunit with a voltage-gated potassium channel complex of pore-forming alpha subunits. Modulates the gating kinetics and enhances stability of the channel complex. Assembled with KCNB1 modulates the gating characteristics of the delayed rectifier voltage-dependent potassium channel KCNB1 (PubMed:12954870) . Associated with KCNC4/Kv3.4 is proposed to form the subthreshold voltage-gated potassium channel in skeletal muscle and to establish the resting membrane potential (RMP) in muscle cells. Associated with KCNQ1/KCLQT1 may form the intestinal cAMP-stimulated potassium channel involved in chloride secretion that produces a current with nearly instantaneous activation with a linear current-voltage relationship.
