Human KCNG3-Strep full length protein-synthetic nanodisc

Voltage-gated potassium (Kv) channels represent the most complex class of voltage-gated ion channels from both functional and structural standpoints. Their diverse functions include regulating neurotransmitter release, heart rate, insulin secretion, neuronal excitability, epithelial electrolyte transport, smooth muscle contraction, and cell volume. This gene encodes a member of the potassium channel, voltage-gated, subfamily G. This member is a gamma subunit functioning as a modulatory molecule. Alternative splicing results in two transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]. Human KCNG3-Strep full length protein-synthetic nanodisc. Protein function: Potassium channel subunit that does not form functional channels by itself (PubMed:11852086). Can form functional heterotetrameric channels with KCNB1, this promotes a reduction in the rate of activation and inactivation of the delayed rectifier voltage- gated potassium channel KCNB1 (PubMed:11852086, PubMed:19074135).
