 16-40 1.26e-07

juxtamembrane and transmembrane (JMTM) domain found in amyloid-beta precursor protein (APP) and similar proteins; Amyloid-beta precursor protein (APP), also called APPI, ABPP, Alzheimer disease amyloid protein, amyloid precursor protein, amyloid-beta A4 protein, cerebral vascular amyloid peptide (CVAP), PreA4, or protease nexin-II (PN-II), functions as a cell surface receptor and performs physiological functions on the surface of neurons relevant to neurite growth, neuronal adhesion and axonogenesis. Amyloid-beta peptides are lipophilic metal chelators with metal-reducing activity; they bind transient metals such as copper, zinc and iron. This model corresponds to juxtamembrane and transmembrane (JMTM) domain of APP, which consists of the intact transmembrane (TM) domain with adjacent N-terminal juxtamembrane (JM) region. More than half of all familial APP mutations of Alzheimer's disease are seen in its JMTM domain region.

juxtamembrane and transmembrane (JMTM) domain found in Notch and APP family proteins; The ...
 17-40 8.44e-03

juxtamembrane and transmembrane (JMTM) domain found in Notch and APP family proteins; The substrates of gamma-secretase include amyloid precursor protein (APP) and the Notch receptor. APP, also called APPI, or Alzheimer disease amyloid protein (ABPP), or amyloid precursor protein, or amyloid-beta A4 protein, or cerebral vascular amyloid peptide (CVAP), or PreA4, or protease nexin-II (PN-II), functions as a cell surface receptor and performs physiological functions on the surface of neurons relevant to neurite growth, neuronal adhesion and axonogenesis. Notch proteins are a family of type-1 transmembrane proteins that form a core component of the Notch signaling pathway. They operate in a variety of different tissues and play a role in a variety of developmental processes by controlling cell fate decisions. Successive cleavage of the APP carboxyl-terminal fragment generates amyloid-beta (Abeta) peptides of varying lengths. Accumulation of Abeta peptides such as Abeta42 and Abeta43 leads to formation of amyloid plaques in the brain, a hallmark of Alzheimer's disease. Notch cleavage is involved in cell-fate determination during development and neurogenesis. The model corresponds to the juxtamembrane and transmembrane (JMTM) domain found in Notch and APP family proteins. It comprises a transmembrane helix (TM) with adjacent juxtamembrane (JM) regions. The JMTM domain is likely to be recognized by gamma-secretase in a similar fashion to both Notch and APP family proteins.
