Application Abreviews Notes
WB Use a concentration of 0.5 - 2 µg/ml. Detects a band of approximately 32 kDa (predicted molecular weight: 29 kDa).


  • 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.
  • Tissue specificity
    Widely expressed. Expressed in leukocytes, lung, placenta, small intestine, liver, kidney, spleen thymus, skeletal muscle, heart and brain. Isoform 1 and isoform 2 are nearly expressed at the same level.
  • Sequence similarities
    Belongs to the APH-1 family.
  • Cellular localization
    Endoplasmic reticulum membrane. Golgi apparatus > Golgi stack membrane. Predominantly located in the endoplasmic reticulum and in the cis-Golgi.
