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. {ECO:0000269PubMed:10676964, ECO:0000269PubMed:11423117, ECO:0000269PubMed:12829703}.
Subcellular Localization Cell membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}.
Disease Associations
Tissue Specificity Isoform 1 and isoform 2 are expressed in brain and kidney. Isoform 1 is also expressed in liver, pancreas, skeletal muscle, small intestine and testis. Isoform 2 is also expressed in lung, pancreas, leukocytes, prostate and thymus.
