Protein
Calcium-activated potassium channel slo-1
Organism
Caenorhabditis elegans
Function
Potassium channel activated by both membrane depolarization or increase in cytosolic Ca(2+) that mediates export of K(+) (PubMed:11738032). Its activation dampens the excitatory events that elevate the cytosolic Ca(2+) concentration and/or depolarize the cell membrane (PubMed:11738032). It therefore contributes to repolarization of the membrane potential (PubMed:11738032). Essential for the regulation of neurotransmitter release at synapses (PubMed:11738032, PubMed:28168949).
Similarity
Belongs to the potassium channel family. Calcium-activated (TC 1.A.1.3) subfamily. Slo sub-subfamily.
