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:0015205 Enables the transfer of a nucleobase, any nitrogenous base that is a constituent of a nucleoside, nucleotide, or nucleic acidfrom one side of a membrane to the other. GO:0015851 The directed movement of a nucleobase, any nitrogenous base that is a constituent of a nucleoside, nucleotide, or nucleic acid, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. GO:0022857 Enables the transfer of a substance, usually a specific substance or a group of related substances, from one side of a membrane to the other. GO:0055085 The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other. GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it.

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.

55 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.
