Summaries for GSAP Gene

Entrez Gene Summary for GSAP Gene

  • Accumulation of neurotoxic amyloid-beta is a major hallmark of Alzheimer disease (AD; MIM 104300). Formation of amyloid-beta is catalyzed by gamma-secretase (see PSEN1; MIM 104311), a protease with numerous substrates. PION, or GSAP, selectively increases amyloid-beta production through a mechanism involving its interaction with both gamma-secretase and its substrate, the amyloid-beta precursor protein (APP; MIM 104760) C-terminal fragment (APP-CTF) (He et al., 2010 [PubMed 20811458]).[supplied by OMIM, Nov 2010]

GeneCards Summary for GSAP Gene

GSAP (Gamma-Secretase Activating Protein) is a Protein Coding gene. Diseases associated with GSAP include alzheimer disease. GO annotations related to this gene include beta-amyloid binding.

UniProtKB/Swiss-Prot for GSAP Gene

  • 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.

    Size:
    854 amino acids
    Molecular mass:
    97802 Da
    Quaternary structure:
    • Interacts with APP; specifically interacts with the CTF-alpha product of APP. Interacts with the gamma-secretase complex.
    Miscellaneous:
    • Its role as an activator of beta-amyloid protein production makes it a promising therapeutic target for the treatment of Alzheimer disease.
    • The gamma-secretase regulator activity is specifically inhibited by imatinib (also known as STI571 or Gleevec), an anticancer drug that selectively decreases beta-amyloid protein production. Imatinib binds PION/GSAP and acts by preventing PION/GSAP interaction with the gamma-secretase substrate, CTF-alpha (PubMed:20811458).
