Gene Information

General description

Presenilin enhancer γ-secretase subunit (Pen-2/ PSENEN) gene, with four exons spanning 1.4 kb, is mapped to human chromosome 19q13.12. Pen-2 is an integral membrane protein with 101 amino acids. The protein is characterized with two transmembrane domains and a cytosolic loop domain, with the C- and N-termini facing the lumen of the endoplasmic reticulum.

Specificity

Anti-PEN2 antibody recognizes Pen-2 (10 kDa).

Immunogen

synthetic peptide encoding amino acids 86-101 located at the C-terminus of human pen-2, conjugated to KLH. This sequence is identical in mouse pen-2.

Application

Anti-Pen-2 antibody produced in rabbit has been used in immunoblotting.

Biochem/physiol Actions

Pen-2 is a critical component of the presenilin (PS)1/γ-secretase and PS2/γsecretase complexes. siRNA interference mediated down regulation of pen-2 is due to reduced PS levels, impaired nicastrin (Nct) maturation and deficient γ secretase complex formation. Pen-2 preferentially interacts with PS1 and induce PS1 endoproteolysis. In addition, it also stabilizes PS fragment heterodimer within the γ-secretase complex subsequent to PS endoproteolysis. PEN-2 plays a vital role in γ-secretase complex maturation in the absence of PS endoproteolysis. Mutation in the PEN-2 gene leads to the development of familial comedones syndrome.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage freeze in working aliquots. Repeated freezing and thawing is not recommended. Storage in "frost-free" freezers is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.

The Alzheimer disease-associated presenilin (PS) proteins apparently provide the active site of gamma-secretase, an unusual intramembrane-cleaving aspartyl protease. PSs principally occur as high molecular weight protein complexes that contain nicastrin (Nct) and additional so far unidentified components. Recently, PEN-2 has
