CC -!- FUNCTION: [Envelope protein E]: Binds to host cell surface receptor and
CC mediates fusion between viral and cellular membranes. Envelope protein
CC is synthesized in the endoplasmic reticulum in the form of heterodimer
CC with protein prM. They play a role in virion budding in the ER, and the
CC newly formed immature particle is covered with 60 spikes composed of
CC heterodimer between precursor prM and envelope protein E. The virion is
CC transported to the Golgi apparatus where the low pH causes dissociation
CC of PrM-E heterodimers and formation of E homodimers. prM-E cleavage is
CC ineficient, and many virions are only partially matured. These
CC uncleaved prM would play a role in immune evasion.
CC {ECO:0000250|UniProtKB:P17763}.
CC -!- SUBUNIT: [Envelope protein E]: Homodimer; in the endoplasmic reticulum
CC and Golgi. {ECO:0000250|UniProtKB:P17763}.
CC -!- SUBCELLULAR LOCATION: [Envelope protein E]: Virion membrane
CC {ECO:0000305}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:P03314}. Host endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:P03314}; Multi-pass membrane protein
CC {ECO:0000255}. Note=ER membrane retention is mediated by the
CC transmembrane domains. {ECO:0000250|UniProtKB:P03314}.
CC -!- PTM: [Envelope protein E]: N-glycosylated.
CC {ECO:0000250|UniProtKB:P17763}.
