DESCRIPTION

Also known as KCNE1_HUMAN, KCNE1. 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:19219384). Assembled with KCNQ1/KVLQT1 is proposed to form the slowly activating delayed rectifier cardiac potassium (IKs) channel. The outward current reaches its steady state only after 50 seconds. Assembled with KCNH2/HERG may modulate the rapidly activating component of the delayed rectifying potassium current in heart (IKr). Interacts with KCNB1. Interacts with KCNC2 (By similarity). Associates with KCNH2/HERG (PubMed:9230439). Interacts with KNCQ1; targets the complex KNCQ1-KCNE1 to the membrane raft (PubMed:20533308). The complex KNCQ1-KNCE1 interacts with the scolopendra toxin SSD609 (PubMed:26307551).
