Figure 6 ( a ) Superimposition of Nek2 (PDB ID: 2JAV), EGFR (PDB ID: 2JIV) and HER2 (PDB ID: 3PP0) kinases.
While the sequence alignments of Nek2 (PDB ID: 2JAV) 14 with that of EGFR (PDB ID: 2JIV) 28 and HER2 (PDB ID: 3PP0) 29 revealed only 22% sequence identity (45% sequence similarity) and 27% sequence identity (49% sequence similarity), respectively, the tertiary folds were remarkably similar ( Figure 6a and Supplementary Figure S1 ).

The preparation of protein The atomic coordinate of HER2 tyrosine kinase domain (HER2-TK) was obtained from the crystallographic structure, accession no. 3PP0 in Protein Data Bank (PDB) [ 7 ].
Recently, in 2011, the first HER2-TK structure complex with pyrimidine compound SYR was released (PDB access 3PP0), providing the new understanding of the kinase structure [ 7 ].
