Subcellular location [CC]Cell membrane {ECO:0000269|PubMed:19074135};
Multi-pass membrane protein {ECO:0000305}. Note=Has to be associated with KCNB1 or possibly another partner to get inserted in the plasma membrane. Colocalizes with KCNB1 at the plasma membrane. Remains intracellular in the absence of KCNB1 (PubMed:19074135). {ECO:0000269|PubMed:19074135}.
