1.A.54.1.1
Presenilin-1 (PS-1; STM-1; E5-1; AD) Ca2+ leak channel (part of the γ-secretase complex; expression alters the lipid raft composition in neuronal membranes (Eckert and Müller, 2009)). The first 5 TMSs of presenilin-1 are homologous to the 5 TMS CD47 antigenic protein, a constituent of the osteoclast fusion complex (1.N.1.1.1), and CD47 is therefore a presenilin homologue (unpublished observations).  The active site of gamma-secretase resides in an aqueous catalytic pore within the lipid bilayer and is tapered around the catalytic aspartates (Sato et al. 2006). TMS 6 and TMS 7 contribute to the hydrophilic pore. Residues at the luminal portion of TMS 6 are predicted to form a subsite for substrate or inhibitor binding on the α-helix facing the hydrophilic milieu, whereas those around the GxGD catalytic motif within TMS 7 are water accessible (Sato et al. 2006).
