Comments
[?]
| FUNCTION | Fluoride-specific ion channel. Important for reducing fluoride concentration in the cell, thus reducing its toxicity. |
| CATALYTIC ACTIVITY | Reaction=fluoride(in) = fluoride(out); Xref=Rhea:RHEA:76159, ChEBI:CHEBI:17051; PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:76160; |
| case <FTGroup:1> | |
| ACTIVITY REGULATION | Na(+) is not transported, but it plays an essential structural role and its presence is essential for fluoride channel function. |
| end case | |
| case not defined <Property:Membrane> or <Property:Membrane=1> | |
| SUBCELLULAR LOCATION | Cell membrane; Multi-pass membrane protein. |
| else case <Property:Membrane=2> | |
| SUBCELLULAR LOCATION | Cell inner membrane; Multi-pass membrane protein. |
| end case | |
| SIMILARITY | Belongs to the fluoride channel Fluc/FEX (TC 1.A.43) family. |
