  • Function

    Regulator of gamma-secretase activity, which specifically activates the production of beta-amyloid protein (beta-amyloid protein 40 and beta-amyloid protein 42), without affecting the cleavage of other gamma-secretase targets such has Notch. The gamma-secretase complex is an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptors and APP (beta-amyloid precursor protein). Specifically promotes the gamma-cleavage of APP CTF-alpha (also named APP-CTF) by the gamma-secretase complex to generate beta-amyloid, while it reduces the epsilon-cleavage of APP CTF-alpha, leading to a low production of AICD.
  • Tissue specificity

    Widely expressed.
  • Sequence similarities

    Belongs to the GSAP family.
  • Post-translational

    The protein is first synthesized as a holoprotein form of 98 kDa and rapidly processed into the gamma-secretase-activating protein 16 kDa C-terminal form, which constitutes the predominant form.
  • Cellular localization

    Golgi apparatus > trans-Golgi network.

Thank you for contacting us. Unfortunately, the exact immunogen sequence is proprietary and we are not able to disclose it. However, if you please could send me the sequence of the 16 kDa C-terminal fragment of PION that you would like to check against the immunogen, I can have the lab check the homology for you. I hope this information is of some help to you. Please do not hesitate to contact us if you need any more advice or information.
