Gamma-secretase subunit APH-1B

UniProtKB accession:  Q8WW43

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Probable subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral proteins such as Notch receptors and APP (amyloid-beta precursor protein). 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.
