Abstract excerpt
APH-1 is one of the four essential components of presenilin (PS)-gamma-secretase complexes. There are three major isoforms of APH-1 in humans: APH-1aS, APH-1aL, and APH-1b. To gain insight into the functional role of APH-1 in gamma-secretase complexes, we analyzed the relationship between the three APH-1 forms and characterized APH-1 mutants with a disrupted transmembrane GxxxG motif. We found that overexpression...
