| + | == Function == | ||
| + | [https://www.uniprot.org/uniprot/GLYCP_HENDH GLYCP_HENDH] Attaches the virus to sialic acid-containing cell receptors and thereby initiating infection. Binding of glycoprotein G to the receptor induces a conformational change that allows the F protein to trigger virion/cell membranes fusion (By similarity). | ||

| + | == Publication Abstract from PubMed == | ||
| + | Hendra virus and Nipah virus, comprising the genus Henipavirus, are recently emerged, highly pathogenic and often lethal zoonotic agents against which there are no approved therapeutics. Two surface glycoproteins, the attachment (G) and fusion (F), mediate host cell entry. The crystal structures of the Hendra G glycoprotein alone and in complex with the ephrin-B2 receptor reveal that henipavirus uses Tryptophan 122 on ephrin-B2/B3 as a "latch" to facilitate the G-receptor association. Structural-based mutagenesis of residues in the Hendra G glycoprotein at the receptor binding interface document their importance for viral attachments and entry, and suggest that the stability of the Hendra-G-ephrin attachment complex does not strongly correlate with the efficiency of viral entry. In addition, our data indicates that conformational rearrangements of the G glycoprotein head domain upon receptor binding may be the trigger leading to the activation of the viral F fusion glycoprotein during virus infection. | ||
