KCNA1 (potassium voltage-gated channel, shaker-related subfamily, member 1) Blocking Peptide (the middle region of protein) (100ug)

Format

Lyophilized powder

Target

KCNA1 mediates the voltage-dependent potassium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a potassium-selective channel through which potassium ions may pass in accordance with their electrochemical gradient.This gene encodes a voltage-gated delayed potassium channel that is phylogenetically related to the Drosophila Shaker channel. The encoded protein has six putative transmembrane segments (S1-S6), and the loop between S5 and S6 forms the pore and contains the conserved selectivity filter motif (GYGD). The functional channel is a homotetramer. The N-terminus of the channel is associated with beta subunits that can modify the inactivation properties of the channel as well as affect expression levels. The C-terminus of the channel is complexed to a PDZ domain protein that is responsible for channel targeting. Mutations in this gene have been associated with myokymia with periodic ataxia (AEMK). Sequence Note: This RefSeq record was created largely from genomic sequence because transcripts were not available for the entire length of the gene. This transcript is supported by sequences from mouse. Publication Note: This RefSeq record includes a subset of the publications that are available for this gene.
