Kv channel-interacting protein 4 (KCNIP4)

Regulatory subunit of Kv4/D (Shal)-type voltage-gated rapidly inactivating A-type potassium channels. Modulates KCND2 channel density, inactivation kinetics and rate of recovery from inactivation at a calcium-dependent and isoform-specific manner (PubMed:11847232, PubMed:18957440, PubMed:23576435).

Modulates KCND3/Kv4.3 currents (PubMed:23576435).
