Entrez Gene summary for PSEN2:
Alzheimer's disease (AD) patients with an inherited form of the disease carry mutations in the presenilin proteins
(PSEN1 or PSEN2) or the amyloid precursor protein (APP). These disease-linked mutations result in increased production
of the longer form of amyloid-beta (main component of amyloid deposits found in AD brains). Presenilins are postulated
to regulate APP processing through their effects on gamma-secretase, an enzyme that cleaves APP. Also, it is thought
that the presenilins are involved in the cleavage of the Notch receptor such that, they either directly regulate
gamma-secretase activity, or themselves act are protease enzymes. Two alternatively spliced transcript variants
encoding different isoforms of PSEN2 have been identified. (provided by RefSeq, Jul 2008)

UniProtKB/Swiss-Prot: PSN2_HUMAN, P49810
Function: Probable catalytic subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the
intramembrane cleavage of integral membrane proteins such as Notch receptors and APP (beta-amyloid precursor protein).
Requires the other members of the gamma-secretase complex to have a protease activity. May play a role in
intracellular signaling and gene expression or in linking chromatin to the nuclear membrane. May function in the
cytoplasmic partitioning of proteins

summary for PSEN2:
Secretases are a group of enzymes involved in the proteolytic cleavage of amyloid precursor protein (APP).
There are three types of secretases, alpha-secretase, beta-secretase and gamma-secretase. gamma-Secretase is
a multi-subunit internal protease that cleaves within the transmembrane domain of its substrates. It is
itself an integral membrane protein and minimally consists of four proteins; presenilin, nicastrin, APH-1
and PEN-2. Presenilin is an aspartic protease and the catalytic subunit of the complex. There are two
important substrates of gamma-secretase; amyloid precursor protein (APP) and Notch. gamma-secretase can
cleave several sites within APP, and the most common products are Abeta40 and Abeta42. Abeta42 is
fibrillogenic and associated with disease states, notably Alzheimer's disease. gamma-Secretase catalyzes the
second step in Notch protein cleavage. gamma-Secretase cleaves within the transmembrane domain of Notch,
releasing the intracellular domain (Nbeta) into the cytoplasm. Nbeta moves to the nucleus where it can
regulate gene expression by activating the transcription factor CSL. This gamma-secretase-Notch signaling
pathway has a role in promoting angiogenesis in the embryo and wound healing in the adult.

  • Defects in PSEN2 are the cause of Alzheimer disease type 4 (AD4) [MIM:606889]. AD is an autosomal dominant
  • Alzheimer disease. Alzheimer disease is a neurodegenerative disorder characterized by progressive dementia, loss of
    cognitive abilities, and deposition of fibrillar amyloid proteins as intraneuronal neurofibrillary tangles,
    extracellular amyloid plaques and vascular amyloid deposits. The major constituent of these plaques is the neurotoxic
    amyloid-beta-APP 40-42 peptide (s), derived proteolytically from the transmembrane precursor protein APP by sequential
    secretase processing. The cytotoxic C-terminal fragments (CTFs) and the caspase-cleaved products such as C31 derived
    from APP, are also implicated in neuronal death
  • Defects in PSEN2 are the cause of cardiomyopathy dilated type 1V (CMD1V) [MIM:613697]. It is a disorder
  • characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and
    arrhythmia. Patients are at risk of premature death
