(A) SiteMap was used to explore potential binding sites in the SHP2 receptor for computational docking studies. Five possible binding sites were identified. The characters of potential binding sites were assessed by calculating various properties, such as size, volume, amino acid exposure, enclosure, contact, hydrophobicity, hydrophilicity, and donor/acceptor ratio. Site 1 in SHP2 was chosen for subsequent CADD in silico database screening. (B) Comparison between Site 1 in SHP2 and a corresponding site in SHP1. Different amino acid sequences between SHP2 and SHP1 are shown in green cartoons and key residues are shown in green carbon sticks.
