Functional Annotations

Enzyme classification and Gene Ontology terms linked to this protein.

13 GO

Gene Ontology (GO)

13
  • 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:0019899 Binding to an enzyme, a protein with catalytic activity.
  • GO:0006812 The directed movement of a monoatomic cation, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Monatomic cations (also called simple cations) are positively charged ions consisting of exactly one atom.
  • GO:0015297 Enables the active transport of a solute across a membrane by a mechanism whereby two or more species are transported in opposite directions in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy. The reaction is: solute A(out) + solute B(in) = solute A(in) + solute B(out).
  • GO:0015643 Binding to a toxic substance, a poisonous substance that causes damage to biological systems.
  • GO:0015503 Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: K+(in) + H+(out) = K+(out) + H+(in), where glutathione maintains the closed state.
  • GO:0008324 Enables the transfer of cation from one side of a membrane to the other.
  • GO:1902600 The directed movement of a proton across a membrane.
  • GO:0015079 Enables the transfer of potassium ions (K+) 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:0006813 The directed movement of potassium ions (K+) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
  • GO:0055085 The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other.
  • GO:0051595 Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a methylglyoxal stimulus. Methylglyoxal is a 2-oxoaldehyde derived from propanal.
