Mitochondrial Membrane Protein

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** Including many peripheral or integral membrane-associated enzymes and transport proteins, Mitochondrial Membrane Proteins are found associated with the smooth outer coat or the highly invaginated inner membrane (cristae) of the semiautonomous, self-reproducing cytoplasmic organelles that constitute the principal site of oxidative phosphorylation (ATP formation) for cellular energy in eukaryotic cells.
