Figure 1. Mitochondrial targeting signals in alpha synuclein and APP proteins.
A, Physico-chemical similarities of N-terminal 32 aminoacid sequence of human alpha synuclein with mitochondrial targeting signals of human P40Scc and P450 c27. (B) Comparison of N-terminal chimeric signals of P450 1A1, 2B1, 2E1 and 2D6 with N-terminus of APP comprising of hydrophobic ER-targeting domain followed by the positively charged mitochondrial-targeting domain.
