Anti-Presenilin Enhancer Protein 2 (PEN2, PEN-2, Gamma-secretase Subunit PEN-2, MDS033, PSENEN)

Gamma-secretase subunit PSENEN, also called PEN-2 is a 10kD member of the PEN-2 family. Human PSENEN is 101aa in length, and is a multi-pass transmembrane protein. Residues 1-17 are on the luminal side of the endoplasmic reticulum or Golgi apparatus, where PSENEN is primarily located. aa18-38 form a transmembrane region, and aa39-60 form a cytoplasmic segment. Another transmembrane segment is formed by residues 61-81, and residues 82-101 are located on the luminal side of the ER or cis-Golgi. Human PSENEN shares 96% aa sequence identity with mouse and rat PSENEN. Functionally, PSENEN is an essential subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptors and beta-amyloid precursor protein.
