Previous GeneCards Identifiers for KCNAB3 Gene
This gene encodes a member of the potassium channel, voltage-gated, shaker-related subfamily. The encoded protein is one of the beta subunits, which are auxiliary proteins associating with functional Kv-alpha subunits. The encoded protein forms a heterodimer with the potassium voltage-gated channel, shaker-related subfamily, member 5 gene product and regulates the activity of the alpha subunit.

KCNAB3 (Potassium Voltage-Gated Channel Subfamily A Regulatory Beta Subunit 3) is a Protein Coding gene. Among its related pathways are Transmission across Chemical Synapses and Potassium Channels. Gene Ontology (GO) annotations related to this gene include voltage-gated potassium channel activity and potassium channel regulator activity. An important paralog of this gene is KCNAB1.
UniProtKB/Swiss-Prot for KCNAB3 Gene
Accessory potassium channel protein which modulates the activity of the pore-forming alpha subunit. Alters the functional properties of Kv1.5.
Voltage-gated potassium channels (KV) belong to the 6-TM family of potassium channel that also comprises the Ca2+-activated Slo (actually 7-TM) and the Ca2+-activated SK subfamilies. The alpha-subunits contain a single pore-forming region and combine to form tetramers.
