Human dipeptidyl peptidase 4 (hDPP4) was recently identified as the receptor for MERS-CoV infection, suggesting that other mammalian DPP4 orthologs may also support infection. We demonstrate that mouse DPP4 cannot support MERS-CoV infection. However, employing mouse DPP4 as a scaffold we identified two critical amino acids (A288L and T330R) that regulate species specificity in the mouse. This knowledge can support the rational design of a mouse adapted MERS-CoV for rapid assessment of therapeutics.
