CC -!- FUNCTION: Probable potassium channel subunit. No channel activity
CC observed in vitro as protein remains in the endoplasmic reticulum. May
CC need to associate with an as yet unknown partner in order to reach the
CC plasma membrane.
CC -!- SUBUNIT: Homodimer. {ECO:0000305}.
CC -!- INTERACTION:
CC Q9Y2U2-2; Q9BXR6: CFHR5; NbExp=3; IntAct=EBI-23647813, EBI-11579371;
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000305}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=3;
CC Name=A;
CC IsoId=Q9Y2U2-1; Sequence=Displayed;
CC Name=B;
CC IsoId=Q9Y2U2-2; Sequence=VSP_006693, VSP_006694;
CC Name=C;
CC IsoId=Q9Y2U2-3; Sequence=VSP_006695, VSP_006696;
CC -!- SIMILARITY: Belongs to the two pore domain potassium channel (TC
CC 1.A.1.8) family. {ECO:0000305}.
