Alzheimer's disease (AD) is characterized by cerebral deposition of β-amyloid (Aβ) peptides. Aβ is released from ectodomain cleaved amyloid precursor protein (APP) via intramembranous proteolysis by γ-secretase, a complex consisting of presenilin and a few other proteins. p23/TMP21, a member of the p24 family type I transmembrane proteins, was recently(More)
Proteolytic processing of amyloid precursor protein (APP) by beta- and gamma-secretases generates beta-amyloid (Abeta) peptides, which accumulate in the brains of individuals affected by Alzheimer disease. Detergent-resistant membrane microdomains (DRM) rich in cholesterol and sphingolipid, termed lipid rafts, have been implicated in Abeta production.(More)
We have developed a system to study human cytomegalovirus (HCMV) cis-acting promoter elements within the context of the viral genome. A recombinant HCMV (RV134) containing a marker gene (beta-glucuronidase) was used to insert HCMV promoter-chloramphenicol acetyltransferase gene constructs into the viral genome between open reading frames US9 and US10. Using(More)
Drosophila Rrp1 protein purified from embryos has four tightly associated enzymatic activities: DNA strand transfer, single-strand DNA renaturation, 3'-exonuclease, and apurinic endonuclease. Copurifying with these activities is a single polypeptide that has an apparent M(r) of 105,000 when estimated by SDS-polyacrylamide gel electrophoresis. To determine(More)
