Protein Structure
|
|
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}.
