| species-specific colocalization of middle east respiratory syndrome coronavirus attachment and entry receptors. | middle east respiratory syndrome coronavirus (mers-cov) uses the s1b domain of its spike protein to bind to dipeptidyl peptidase 4 (dpp4), its functional receptor, and its s1a domain to bind to sialic acids. the tissue localization of dpp4 in humans, bats, camelids, pigs, and rabbits generally correlates with mers-cov tropism, highlighting the role of dpp4 in virus pathogenesis and transmission. however, mers-cov s1a does not indiscriminately bind to all α2,3-sialic acids, and the species-specif ... | 2019 | 31167913 |
