Kv channel-interacting protein 1 (KCNIP1)

Regulatory subunit of Kv4/D (Shal)-type voltage-gated rapidly inactivating A-type potassium channels. Regulates channel density, inactivation kinetics and rate of recovery from inactivation in a calcium-dependent and isoform-specific manner.

In vitro, modulates KCND1/Kv4.1 and KCND2/Kv4.
