It probably represents a stabilizing cofactor for the presenilin homodimer that promotes the formation of a stable complex. Probably present in a minority of gamma-secretase complexes compared to APH1A. {ECO:0000269|PubMed:12297508}. |Aph-1| |gamma-secretase complex| |Notch receptor processing, ligand-dependent| |Notch receptor processing| |membrane protein intracellular domain proteolysis| |membrane protein proteolysis| |endopeptidase activity| |peptidase activity| |ephrin receptor signaling pathway| |transport vesicle| |Notch signaling pathway| |protein processing| |locomotory behavior| |endosome membrane| |protein maturation| |transmembrane receptor protein tyrosine kinase signaling pathway| |behavior| |positive regulation of apoptotic process| |positive regulation of programmed cell death| |positive regulation of cell death| |enzyme linked receptor protein signaling pathway| |endoplasmic reticulum| |proteolysis| |integral component of plasma membrane| |positive regulation of catalytic activity| |regulation of apoptotic process| |regulation of programmed cell death| |regulation of cell death| |positive regulation of molecular function| |gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp103|Taxol 0.004μM R03 exp103]]|1.89| |[[:results:exp362|GSK-J4 1μM R07 exp362]]|2| No correlation found to any other genes in chemogenomics.
