[[http://www.uniprot.org/uniprot/KCIP1_HUMAN KCIP1_HUMAN]] Regulatory subunit of Kv4/D (Shal)-type voltage-gated rapidly inactivating A-type potassium channels. Probably modulates channels 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/Kv4.2 currents. Seems to be involved in KCND2 trafficking to the cell surface.<ref>PMID:10676964</ref> <ref>PMID:11423117</ref> <ref>PMID:12829703</ref> [[http://www.uniprot.org/uniprot/KCND3_HUMAN KCND3_HUMAN]] Pore-forming (alpha) subunit of voltage-gated rapidly inactivating A-type potassium channels.
