Despite its predicted molecular weight, APH1 often migrates at aberrant locations in SDS-PAGE. A suggested positive control is human brain tissue lysate.
PA5-20318 can be used with blocking peptide PEP-0438.
APH1 was initially identified as a component of the Notch pathway in C. elegans. Along with nicastrin, PEN2, and presenilin-1 APH1 is an essential component of the -gamma-secretase complex which cleave the amyloid precursor protein (APP) at what are known as the -gamma- and epsilon-sites and can lead to the accumulation of the Amyloid beta peptide (Abeta) cleavage product that is associated with Alzheimer and quote;s disease. APH1 exists in at least three distinct isoforms with APH1a as the principal isoform present in the -gamma-secretase complex. Mice deficient in this isoform, but not the other two, were lethal at E10.5, with impaired vascular and neural development observed.
