Kv channel-interacting protein 2 (KCNIP2)

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

In vitro, modulates KCND2/Kv4.2 and KCND3/Kv4.
