Summaries for APH1B Gene

Entrez Gene Summary for APH1B Gene

  • This gene encodes a multi-pass transmembrane protein that is a functional component of the gamma-secretase complex, which also contains presenilin and nicastrin. This protein represents a stabilizing cofactor for the presenilin holoprotein in the complex. The gamma-secretase complex catalyzes the cleavage of integral proteins such as notch receptors and beta-amyloid precursor protein. [provided by RefSeq, Sep 2011]

GeneCards Summary for APH1B Gene

APH1B (Aph-1 Homolog B, Gamma-Secretase Subunit) is a Protein Coding gene. Diseases associated with APH1B include Alzheimer Disease. Among its related pathways are Signaling by NOTCH1 and p75 NTR receptor-mediated signalling. Gene Ontology (GO) annotations related to this gene include peptidase activity. An important paralog of this gene is APH1A.

UniProtKB/Swiss-Prot for APH1B Gene

  • 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.
