Any protein maturation process achieved by the cleavage of a peptide bond or bonds within a protein. Protein maturation is the process leading to the attainment of the full functional capacity of a protein.

The formation of a mature peptide mating pheromone by proteolysis and/or modification of a peptide precursor, occurring in the context of conjugation with cellular fusion.

The second process in a series of specific posttranslational modifications to the CAAX box region of CAAX box proteins, in which the last three amino acids of the protein (AAX) are removed by proteolysis.

The inner, i.e. lumen-facing, lipid bilayer of the nuclear envelope.

The outer, i.e. cytoplasm-facing, lipid bilayer of the mitochondrial envelope.

The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).

The component of the endoplasmic reticulum membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
