Protein Structure

UniProt Annotation

Function

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 (By similarity). {ECO:0000250}.

Subcellular Localization

Cell membrane {ECO:0000269PubMed:14572458}; Peripheral membrane protein {ECO:0000269PubMed:14572458}.

Disease Associations

Tissue Specificity

Expressed in brain. Found in a subpopulation of neurons widely distributed and enriched in Purkinje cells of the cerebellum and in the reticular thalamic and medial habenular nuclei. {ECO:0000269PubMed:15363885}.
