Scientific background

Voltage-gated K+ (KV) channels form functional entities by the assembly of four α subunits and auxiliary subunits. Various auxiliary subunits are known to interact with KV channels thereby modulating various properties such as gating, activation and inactivation of the channels as well as influencing trafficking of the channels to the cell’s plasma membrane1.

KChIPs (KV channel interacting proteins) are cytoplasmic proteins which belong to the neural Ca2+ sensor (NCS) family of Ca2+ binding EF-hand proteins. To date, KChIP1-4 have been identified. All four KChIPs have a conserved C-terminal domain, which has four EF-hand-like Ca2+ binding motifs. The N-terminal region differs among the various KChIPs and attributes different properties regarding the regulation of KV channels1. KChIPs regulate different properties of KV channels such as their cell surface expression (mediated by proper trafficking of the various subunits), channel assembly and gating1-4. Specifically, KChIP2, 3 and 4 strongly regulate the activity of the KV4 channel family in cortical pyramidal neurons5. Furthermore, KChIP knockout mice display an increase in anxiety-like behavior compared to their wild type counterparts6.

KChIP1, 3, and 4 are mostly expressed in the brain while KChIP2 is expressed in the heart as well as in the brain4-6.
