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 (APH1B Gamma Secretase Subunit) is a Protein Coding gene. Among its related pathways are PI-3K cascade and Signaling by FGFR. 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 (beta-amyloid 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.

    Quaternary structure:
    • Probable 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 (By similarity). Interacts with PSEN1 and PSEN2.
