PSEN2 (human)

PSEN2 probable catalytic subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptors and APP (beta-amyloid precursor protein). An integral membrane protein of the Golgi and endoplasmic reticulum. Requires the other members of the gamma-secretase complex to have a protease activity. May play a role in intracellular signaling and gene expression or in linking chromatin to the nuclear membrane. May function in the cytoplasmic partitioning of proteins. Two alternative splice isoforms have been identified. Note: This description may include information from UniProtKB.
