8.A.15 The K+ Channel Accessory Protein (KChAP) Family
The KChAP family consists of proteins from yeast, plants and animals. The best characterized homologues are from mammals. KChAP interacts with the Kv2 principal subunits of the VIC superfamily, enhancing current levels and surface expression of Kv2 without affecting gating or kinetics. It may function as a chaperone subunit.
