Presenilin Enhancer 2 (Presenilin Enhancer Protein 2, Presenilin Enhancer 2 Homolog, PEN2, PEN-2, Gamma Secretase Subunit PEN2, Gamma Secretase Subunit PEN-2, Hematopoietic Stem/progenitor Cells Protein MDS033, MDS033, MSTP064, PSENEN) (Not for Export EU)

Presenilin (PS1/PS2) complexes are responsible for the intramembrane gamma-secretase cleavage of the beta-amyloid precursor protein. Presenilin enhancer 2 (PEN2) is an essential cofactor involved in physically interacting with PS1 and is necessary for gamma-secretase activity. Endogenous PEN2 preferentially interacts with PS1 holoprotein. Down-regulation of PEN2 expression abolishes the endoproteolysis of PS1 and overexpression promotes the production of PS1 fragments.||Cellular Localization: Membrane||Applications: |Suitable for use in Western Blot and Immunoprecipitation. Other applications not tested.||Recommended Dilution:|Optimal dilutions to be determined by the researcher.||Storage and Stability:|May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20°C. Aliquots are stable for at least 12 months at -20°C.
