Close relatives of MERS-CoV in bats use ACE2 as their functional receptors (biorxiv.org)

Key take-outs on page 13

"these viruses may hold a latent potential to infect humans through further adaptation via antigenic drift. It is also very likely that their relatives with human emergence potential are circulating somewhere in nature. Overall, we identified ACE2 as a long-sought functional receptor of the potential MERS-CoV ancestors in bats, facilitating the in-depth research of these important viruses with zoonotic emergence risks. Our study adds to the knowledge about the complex receptor usage of coronaviruses, highlighting the importance of surveillance and research on these viruses to prepare for potential outbreaks in the future."
