NCIt definition : A process that involves the proteolysis of an integral membrane protein at a site
that is within its transmembrane domain. This cleavage causes the release of cytosolic
fragments that can enter the nucleus and regulate transcription.;
NCIt note : Regulated intramembrane proteolysis of a transmembrane protein usually follows the
proteolytic shedding of the extracellular domain. Regulated intramembrane proteolysis
is involved in many biological processes including embryonic development, cholesterol
signaling and Alzheimer disease.;
