The aim is to explore how different KChIP1 splice variants influence Kv4 channel inactivation characteristics.
Utilized two-electrode voltage-clamp in Xenopus oocytes
Co-expressed Kv4.1, Kv4.2, Kv4.3 S, and Kv4.3 L with KChIP1 variants
Analyzed binary and ternary channel configurations with DPPs
Kv4.x channels showed a slower recovery from inactivation with KChIP1 splice variant co-expression
KChIP1b exhibited a stronger effect, limiting the fast repetitive availability of A-type currents
Ternary Kv4.2 + DPP + KChIP1b displayed enhanced P/C-type inactivation features
