OS MUS MUSCULUS (MOUSE). OC EUKARYOTA; METAZOA; CHORDATA; VERTEBRATA; TETRAPODA; MAMMALIA; OC EUTHERIA; RODENTIA. RN [1] RP SEQUENCE FROM N.A., AND PARTIAL SEQUENCE. RC TISSUE=HEART; RX MEDLINE; 92007723. RA HONORE E., ATTALI B., ROMEY G., HEURTEAUX C., RICARD P., LESAGE F., RA LAZDUNSKI M., BARHANIN J.; RL EMBO J. 10:2805-2811(1991). RN [2] RP SEQUENCE FROM N.A. RX MEDLINE; 92233938. RA LESAGE F., ATTALI B., LAZDUNSKI M., BARHANIN J.; RL FEBS LETT. 301:168-172(1992). CC -!- FUNCTION: VERY SLOWLY ACTIVATED VOLTAGE-DEPENDENT POTASSIUM CC CHANNEL. THE OUTWARD CURRENT REACHS ITS STEADY STATE ONLY AFTER CC 50 SECONDS. CC -!- SUBCELLULAR LOCATION: TYPE I MEMBRANE PROTEIN. CC -!- SUBUNIT: IT IS NOT YET KNOWN HOW MANY SUBUNITS ARE NECESSARY CC TO FORM A FUNCTIONAL CHANNEL. CC -!- TISSUE SPECIFICITY: RESTRICTIVELY LOCALIZED IN THE APICAL CC MEMBRANE PORTION OF EPITHELIAL CELLS. CC -!- PTM: PHOSPHORYLATION INHIBITS THE POTASSIUM CURRENT (BY CC SIMILARITY). CC -!- SIMILARITY: WITH THE HUMAN AND RAT COUNTERPARTS.
