[https://www.uniprot.org/uniprot/O11875_9FLAV O11875_9FLAV] Envelope protein E binding to host cell surface receptor is followed by virus internalization through clathrin-mediated endocytosis. Envelope protein E is subsequently involved in membrane fusion between virion and host late endosomes. Synthesized as a homodimer with prM which acts as a chaperone for envelope protein E. After cleavage of prM, envelope protein E dissociate from small envelope protein M and homodimerizes (By similarity).[SAAS:SAAS026470_004_099774]

The current Zika virus (ZIKV) epidemic is characterized by severe pathogenicity in both children and adults. Sequence changes in ZIKV since its first isolation are apparent when pre-epidemic strains are compared with those causing the current epidemic. However, the residues that are responsible for ZIKV pathogenicity are largely unknown. Here we report the cryo-electron microscopy (cryo-EM) structure of the immature ZIKV at 9-A resolution. The cryo-EM map was fitted with the crystal structures of the precursor membrane and envelope glycoproteins and was shown to be similar to the structures of other known immature flaviviruses. However, the immature ZIKV contains a partially ordered capsid protein shell that is less prominent in other immature flaviviruses. Furthermore, six amino acids near the interface between pr domains at the top of the spikes were found to be different between the pre-epidemic and epidemic ZIKV, possibly influencing the composition and structure of the resulting viruses.
