Gene Symbol KCNE4
Protein Name potassium voltage-gated channel, Isk-related family, member 4
Synonyms MIRP3;
Species Homo sapiens
Ensembl Protein ENSP00000281830
InnateDB Gene IDBG-82247 (KCNE4)
Protein Structure
UniProt Annotation
Function Ancillary protein that assembles as a beta subunit with a voltage-gated potassium channel complex of pore-forming alpha subunits. Modulates the gating kinetics and enhances stability of the channel complex. May associate with KCNQ1/KVLTQ1 and inhibit potassium current.
Subcellular Localization Membrane {ECO:0000305}; Single-pass membrane protein {ECO:0000305}.
Disease Associations
Tissue Specificity Predominantly expressed in embryo and adult uterus. Low expression found in kidney, small intestine, lung and heart. {ECO:0000269PubMed:12096056}.
