Protein
Potassium voltage-gated channel protein Shab
Organism
Drosophila melanogaster
Function
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.
Similarity
Belongs to the potassium channel family. B (Shab) (TC 1.A.1.2) subfamily. Shab sub-subfamily.
