Triggering the measles virus membrane fusion machinery.
Paramyxoviruses contain glycoprotein fusion machineries that mediate membrane merger for infection. The molecular framework and mechanistic principles governing receptor-induced triggering of the machinery remain unknown. Using measles virus (MeV) fusion complexes, we demonstrate that receptor binding to only one dimer of the tetrameric attachment protein (H) dimer-of-dimers induces fusion-prot...
متن کاملProbing the Spatial Organization of Molecular Complexes Using Triple-Pair-Correlation
Super-resolution microscopy coupled with multiplexing techniques can resolve specific spatial arrangements of different components within molecular complexes. However, reliable quantification and analysis of such specific organization is extremely problematic because it is frequently obstructed by random co-localization incidents between crowded molecular species and the intrinsic heterogeneity...

15 صفحه اولThe molecular length of measles virus RNA and the structural organization of measles nucleocapsids.
Full-length measles virus RNA molecules isolated from purified virions or nucleocapsids and examined by electron microscopy were 5.12(+/- 0.12) micron in length, corresponding to a molecular weight of 5.2 (+/- 0.1) X 10(6). Purified virions examined by negative staining in the electron microscope exhibited a pleomorphic range of particle sizes varying in diameter between 300 nm and 1000 nm. Pur...
متن کاملMeasles virus fusion: role of the cysteine-rich region of the fusion glycoprotein.
Measles virus (MV) fusion requires the participation of both the fusion (F) and hemagglutinin (H) glycoproteins. The canine distemper virus fusion protein (CDVF) cannot substitute for the measles virus fusion protein (MVF) in this process. Introduction of restriction enzyme sites into the cDNAs of CDVF and MVF by site-directed mutagenesis facilitated the production of chimeric F proteins which ...
