Background Information

Adaptor protein FE65 (APBB1) specifically binds to the intracellular tail of the type I transmembrane protein, β-amyloid precursor protein (APP). FE65 is a multimodular adaptor protein, consisting of three major protein-protein interaction domains, a WW domain and two phosphotyrosine interaction domains (PID). The interaction between FE65 and APP mainly takes place between the C-terminal PID (PID2) and the APP intracellular domain (AICD) (PMID: 15647266). There is novel evidence that the major isoform of FE65 (97-kDa FE65, p97FE65) can be converted to a 65-kDa N-terminally truncated C-terminal fragment (p65FE65) via endoproteolysis. The cleavage region locates immediately after an acidic residue cluster but before the three major protein-protein binding domains (PMID: 15647266). FE65 is predominantly expressed in central nervous system neurons, and its expression is regulated during development and aging, with high levels corresponding to the timing of neural tissue formation and high neuronal activity (PMID: 7867517, PMID: 10561691, PMID: 14689444). p65FE65 (65kDa) is endoproteolytically cleaved from p97FE65 (97 kDa), the major isoform of FE65 (97-kDa FE65, p97FE65) can be converted to a 65-kDa N-terminally truncated C-terminal fragment (p65FE65) via endoproteolysis (PMID: 15647266).
