Effect of different InDel rates on TFBS RTR. The x-axis denotes the InDel rate measured by the number of InDel events per substitution events, and the y-axis shows the RTR of a TFBS in a descendent sequence. The figure shows that the exponential model given in equation 5 fits well with the observed RTR values from simulation for all three TFBSs: (a) E2F, (b) Myc, and (c) NFκB.
