pubmed:abstractText |
Alzheimer's disease is characterized by the presence of senile plaques comprised primarily of deposits of the beta-amyloid protein (A beta) derived from larger amyloid precursor proteins (APP). We have identified a cDNA that encodes a 751-amino acid APP-like protein (designated APLP2) from the mouse that, with exception of the A beta region, is highly homologous to APP. In situ hybridization and quantitative polymerase chain reaction reveal that APLP2 and APP mRNA are expressed in similar, if not identical, neuronal populations and at similar levels. APLP2 appears to mature through the same unusual secretory/cleavage pathway as APP. Furthermore, widely utilized antibodies generated against non-overlapping epitopes of APP do not discriminate between APP and APLP2. Although APLP2 cannot give rise to A beta, its near identity to APP outside the A beta domain confounds the interpretation of previous immunocytochemical and biochemical characterizations of APP biosynthesis and metabolism.
