CC -!- FUNCTION: The surface protein (SU) attaches the virus to the host cell
CC by binding to its receptor. This interaction triggers the refolding of
CC the transmembrane protein (TM) and is thought to activate its fusogenic
CC potential by unmasking its fusion peptide. Fusion occurs at the host
CC cell plasma membrane (By similarity). {ECO:0000250}.
CC -!- FUNCTION: The transmembrane protein (TM) acts as a class I viral fusion
CC protein. Under the current model, the protein has at least 3
CC conformational states: pre-fusion native state, pre-hairpin
CC intermediate state, and post-fusion hairpin state. During viral and
CC target cell membrane fusion, the coiled coil regions (heptad repeats)
CC assume a trimer-of-hairpins structure, positioning the fusion peptide
CC in close proximity to the C-terminal region of the ectodomain. The
CC formation of this structure appears to drive apposition and subsequent
CC fusion of viral and target cell membranes. Membranes fusion leads to
CC delivery of the nucleocapsid into the cytoplasm (By similarity).
CC {ECO:0000250}.
CC -!- SUBUNIT: The mature envelope protein (Env) consists of a trimer of SU-
CC TM heterodimers attached by non-covalent interactions or by a labile
CC interchain disulfide bond. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [Transmembrane protein]: Virion membrane
CC {ECO:0000250}; Single-pass type I membrane protein {ECO:0000250}. Host
CC cell membrane {ECO:0000250}; Single-pass type I membrane protein
CC {ECO:0000250}. Note=It is probably concentrated at the site of budding
CC and incorporated into the virions possibly by contacts between the
CC cytoplasmic tail of Env and the N-terminus of Gag. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [Surface protein]: Virion membrane {ECO:0000250};
CC Peripheral membrane protein {ECO:0000250}. Host cell membrane
CC {ECO:0000250}; Peripheral membrane protein {ECO:0000250}. Note=The
CC surface protein is not anchored to the viral envelope, but associates
CC with the extravirion surface through its binding to TM. It is probably
CC concentrated at the site of budding and incorporated into the virions
CC possibly by contacts between the cytoplasmic tail of Env and the N-
CC terminus of Gag (By similarity). {ECO:0000250}.
CC -!- PTM: Specific enzymatic cleavages in vivo yield mature proteins.
CC Envelope glycoproteins are synthesized as an inactive precursor that is
CC N-glycosylated and processed likely by host cell furin or by a furin-
CC like protease in the Golgi to yield the mature SU and TM proteins. The
CC cleavage site between SU and TM requires the minimal sequence [KR]-X-
CC [KR]-R (By similarity). {ECO:0000250}.
