  • Gene name:
    APH1A(CGI-78;UNQ579/PRO1141;PSF);
    Protein name:
    Gamma-secretase subunit APH-1A(APH-1a);
    Alternative:
    Presenilin-stabilization factor;Aph-1alpha;
    Organism:
    Human (Homo sapiens). 
    General Annotation
    Sub Unit:
    Component of the gamma-secretase complex, a complex composed of a presenilin homodimer (PSEN1 or PSEN2), nicastrin (NCSTN), APH1 (APH1A or APH1B) and PEN2. Such minimal complex is sufficient for secretase activity, although other components may exist.
    Function:
    Essential subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral proteins such as Notch receptors and APP (beta-amyloid precursor protein). It probably represents a stabilizing cofactor for the presenilin homodimer that promotes the formation of a stable complex.
    Subcellular Location:
    Endoplasmic reticulum membrane Multi-pass membrane protein Golgi apparatus Golgi stack membrane Multi-pass membrane protein Predominantly located in the endoplasmic reticulum and in the cis-Golgi.
