Target Data

Function Functions as a cell surface receptor and performs physiological functions on the surface of neurons relevant to neurite growth, neuronal adhesion and axonogenesis. Involved in cell mobility and transcription regulation through protein-protein interactions (By similarity). Can promote transcription activation through binding to APBB1-KAT5 and inhibit Notch signaling through interaction with Numb (By similarity). Couples to apoptosis-inducing pathways such as those mediated by G(O) and JIP. Inhibits G(o) alpha ATPase activity. Acts as a kinesin I membrane receptor, mediating the axonal transport of beta-secretase and presenilin 1 (By similarity). May be involved in copper homeostasis/oxidative stress through copper ion reduction. Can regulate neurite outgrowth through binding to components of the extracellular matrix such as heparin and collagen I and IV (By similarity). The splice isoforms that contain the BPTI domain possess protease inhibitor activity. Induces a AGER-dependent pathway that involves activation of p38 MAPK, resulting in internalization of amyloid-beta peptide and leading to mitochondrial dysfunction in cultured mitochondrial dysfunction in cultured cortical neurons. Provides Cu(2+) ions for GPC1 which are required for release of nitric oxide (NO) and subsequent degradation of the heparan sulfate chains on GPC1 (By similarity).
Gene References into Functions
  1. These results, in Wistar rats, provide experimental support for the hypothesis that certain risk factors, such as energy metabolism dysfunction or the aging process itself, may increase vulnerability to beta-amyloid protein (Abeta). Hippocampal region is more susceptible to Abeta and its effect increases with age in relation to the neocortex. PMID: 29624358
  2. Abeta 25-35 was found to induce PC12 cell apoptosis in a dose-dependent manner (P<0.05). Moreover, Abeta 25-35 also caused dose-dependent disintegration of the cytoskeleton (P<0.05). PMID: 29436599

  6. Results from the present study indicated that pioglitazone may improve insulin sensitivity and ameliorate Abeta42 accumulation in rats with dietinduced IR by regulating AKT/GSK3beta activation, suggesting that pioglitazone may be a promising drug for AD treatment. PMID: 28447730

  8. Results show that concerted signaling by both APP and Abeta is necessary for aberrant neuronal cell cycle entry. Thus, APP plays a central role in promotion of neurodegeneration, through activation of Ras-ERK signaling axis as well as GSK-3, and interfering with these signaling events would impede cell cycle reentry and neurodegeneration observed in Alzheimer's disease.
