p(HGNC:BACE1) increases sec(a(HBP:"sAPP-beta"))
Transient transfection of SH-SY5Y APP-695 cells with Asp 2 (Fig. 2a) results in a significant increase in the secretion of sAPPb (Fig. 2b) consistent with Asp 2 being b-secretase. To demonstrate that this increase in sAPPb is linked to the proteolytic activity of Asp 2, we mutated each of the proposed catalytic aspartic residues at positions 25 and 215 (determined by comparison with the position of the known catalytic aspartyl residues in pepsin) to asparagine. Both mutants and the wild-type Asp 2 are expressed to similar levels (Fig. 2a).
