Functional Annotations

Enzyme classification and Gene Ontology terms linked to this protein.

12 GO

Gene Ontology (GO)

12
  • GO:1904680 Enables the transfer of a peptide 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.
  • 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.
  • GO:0015833 The directed movement of peptides, compounds of two or more amino acids where the alpha carboxyl group of one is bound to the alpha amino group of another, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
  • GO:0006857 The directed movement of oligopeptides into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Oligopeptides are molecules that contain a small number (2 to 20) of amino-acid residues connected by peptide linkages.
  • 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:0071916 Enables the transfer of a dipeptide from one side of a membrane to the other. A dipeptide is a combination of two amino acids linked together by a peptide (-CO-NH-) bond.
  • GO:0015333 Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: peptide(out) + H+(out) = peptide(in) + H+(in), up its concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction and is driven by hydrogen ion movement.
  • GO:0042937 Enables the transfer of a tripeptide, a compound containing three amino acids linked together by peptide bonds, from one side of a membrane to the other.
  • GO:0015031 The directed movement of proteins into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
  • GO:0035443 The directed movement of a tripeptide across a membrane by means of some agent such as a transporter or pore. A tripeptide is a compound containing three amino acids linked together by peptide bonds.
