DUF1211

DUF1211
PFAM accession number:PF06736
Interpro abstract (IPR010617):

In animals, TMEM175 is an organelle-specific potassium channel specifically responsible for potassium conductance in endosomes and lysosomes. It forms a potassium-permeable leak-like channel, which regulates lumenal pH stability and is required for autophagosome-lysosome fusion. TMEM175 is the major lysosomal K+ conductance [(PUBMED:26317472)].

This entry also includes TMEM175 homologues from bacteria and archaea.

GO function:potassium channel activity (GO:0005267)
