  1. APL-1: amyloid precursor like 1 protein; APPL-1: AβPP-like 1 protein; AβPP: amyloid-β precursor protein; APLP-2: amyloid precursor protein like protein 2; APLP-1: amyloid precursor protein like protein 1. This table shows the percentage of synapomorphy accounted for by the N-terminal signal peptide and the three major conserved regions of the peptide sequences for the entire phyologenetic tree and the relative contribution for the five major branches.
