This entry represents the short N-terminal helical domain of Shal-type voltage-gated potassium channels. The domain interacts with Kv channel-interacting proteins to modulate cell surface expression and the function of Kv4 channels. The interaction of the N-terminus of Shal-type protein Kv4.2 and the Kv interacting protein KChiP1 forms a structure which is like the structure between calmodulin and its target peptides when they interact. Interactions of an N terminal alpha helix in Kv4.2 and a C terminal alpha helix in KChIP1 are essential for the modulation of Kv4.2 by KChIPs [1].
