GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. GO:0062054 Enables the energy-independent facilitated diffusion of a fluoride ion through a transmembrane aqueous pore or channel. GO:1903425 Enables the transfer of fluoride from one side of a membrane to the other. GO:0046872 Binding to a metal ion. GO:0140114 Any process carried out at the cellular level that reduces or removes the toxicity of a fluoride. These may include chemical modification or transport of fluoride away from sensitive areas and to compartments or complexes whose purpose is sequestration of the toxic substance. GO:1903424 The process in which fluoride is transported across a membrane.

Ligand evidence

Ligands grouped by evidence source. PDB ligands keep the source crystal visible, and loaded crystals can be opened directly in the structure viewer.

52 records

Highest-confidence structural evidence: ligands co-crystallized with this exact protein. If the source PDB is loaded in TPW, use Open crystal to inspect it in the structure viewer.

No PDB structure with a co-crystallized ligand found for this exact protein.

Structural evidence inferred from similar proteins. The source crystal indicates where the ligand was observed; the UniProt column identifies the homologous protein carrying that ligand.
