Functional Annotations

Enzyme classification and Gene Ontology terms linked to this protein.

5 GO

Gene Ontology (GO)

5
  • 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:0042910 Enables the directed movement of a xenobiotic from one side of a membrane to the other. A xenobiotic is a compound foreign to the organism exposed to it. It may be synthesized by another organism (like ampicilin) or it can be a synthetic chemical.
  • GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it.
  • GO:0055085 The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other.
  • 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.
