potassium channel subfamily U member 1 [Mus musculus]

Protein Classification

calcium-activated potassium channel( domain architecture ID 11999068)

calcium-activated potassium channel similar to Drosophila melanogaster slowpoke (dSlo) that is activated by both membrane depolarization or increase in cytosolic Ca(2+) that mediates export of K(+)

104-323 2.60e-15

Ion transport protein; This family contains sodium, potassium and calcium ion channels. This family is 6 transmembrane helices in which the last two helices flank a loop which determines ion selectivity. In some sub-families (e.g. Na channels) the domain is repeated four times, whereas in others (e.g. K channels) the protein forms as a tetramer in the membrane.
