CC -!- FUNCTION: Class I viral fusion protein. Under the current model, the
CC protein has at least 3 conformational states: pre-fusion native state,
CC pre-hairpin intermediate state, and post-fusion hairpin state. During
CC viral and plasma cell membrane fusion, the heptad repeat (HR) regions
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 plasma cell membranes. Directs fusion of viral and
CC cellular membranes leading to delivery of the nucleocapsid into the
CC cytoplasm. This fusion is pH independent and occurs directly at the
CC outer cell membrane. The trimer of F1-F2 (F protein) probably interacts
CC with HN at the virion surface. Upon HN binding to its cellular
CC receptor, the hydrophobic fusion peptide is unmasked and interacts with
CC the cellular membrane, inducing the fusion between cell and virion
CC membranes. Later in infection, F proteins expressed at the plasma
CC membrane of infected cells could mediate fusion with adjacent cells to
CC form syncytia, a cytopathic effect that could lead to tissue necrosis
CC (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homotrimer of disulfide-linked F1-F2. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000250}; Single-pass type I
CC membrane protein {ECO:0000250}. Host cell membrane {ECO:0000250};
CC Single-pass membrane protein {ECO:0000250}.
CC -!- PTM: The inactive precursor F0 is glycosylated and proteolytically
CC cleaved into F1 and F2 to be functionally active. The cleavage is
CC mediated by cellular proteases during the transport and maturation of
CC the polypeptide (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the paramyxoviruses fusion glycoprotein family.
CC {ECO:0000305}.
