MGC4618, Hypothetical protein DKFZp547K246, hypothetical protein LOC84286, Hypothetical protein MGC4618, TM175_HUMAN, tmem175, Transmembrane protein 175.
Organelle-specific potassium channel specifically responsible for potassium conductance in endosomes and lysosomes. Forms a potassium-permeable leak-like channel, which regulates lumenal pH stability and is required for autophagosome-lysosome fusion. Constitutes the major lysosomal potassium channel.
