Figure 3.

Comparison of the amino acid sequence of the DNA-PKcs between human and mouse. All amino acid residues are indicated by three symbols; vertical bars (∥) are for the identical residues and small horizontal bars (−) are for the residues with similar biochemical features; spaces are for the residues with no similarity between the human and mouse counterparts. There are some extremely conserved regions, which are surrounded by open squares. Solid bars (▪) are for the consensus sequence of PI3K.
