Fig. 1. Process of human IAPP precursor processing to form mature IAPP and homology comparison of IAPP mature proteins in different species.

Fig. 1

a Human IAPP was processed to form mature IAPP. The signal peptide consisting of 22 amino acid residues is represented by blue, the flanking regions of the original N-terminal and C-terminal regions of IAPP are indicated by green, and the mature peptide sequences are indicated by red. b Comparison and analysis of amino acid sequence homology of mature IAPP proteins between different species. c Unrooted tree of IAPP mature protein between different species
