Direct measurement of Gag–Gag interaction during retrovirus assembly with FRET and fluorescence correlation spectroscopy
During retrovirus assembly, the polyprotein Gag directs protein multimerization, membrane binding, and RNA packaging. It is unknown whether assembly initiates through Gag-Gag interactions in the cytosol or at the plasma membrane. We used two fluorescence techniques-two-photon fluorescence resonance energy transfer and fluorescence correlation spectroscopy-to examine Rous sarcoma virus Gag-Gag a...
متن کاملMicroRNA binding to the HIV-1 Gag protein inhibits Gag assembly and virus production.
MicroRNAs (miRNAs) are small, 18-22 nt long, noncoding RNAs that act as potent negative gene regulators in a variety of physiological and pathological processes. To repress gene expression, miRNAs are packaged into RNA-induced silencing complexes (RISCs) that target mRNAs for degradation and/or translational repression in a sequence-specific manner. Recently, miRNAs have been shown to also inte...
متن کاملNew Insights into HTLV-1 Particle Structure, Assembly, and Gag-Gag Interactions in Living Cells
Human T-cell leukemia virus type 1 (HTLV-1) has a reputation for being extremely difficult to study in cell culture. The challenges in propagating HTLV-1 has prevented a rigorous analysis of how these viruses replicate in cells, including the detailed steps involved in virus assembly. The details for how retrovirus particle assembly occurs are poorly understood, even for other more tractable re...
متن کاملAssembly of human immunodeficiency virus precursor gag proteins.
To investigate the mechanism by which human immunodeficiency virus (HIV) precursor Gag (PrGag) proteins assemble to form immature virus particles, we examined the in vitro assembly of MACANC proteins, composed of the PrGag matrix, capsid, and nucleocapsid domains. In the absence of other components, MACANC proteins assembled efficiently at physiological temperature but inefficiently at lower te...
متن کاملQuantum gauging from classical gauging of nonlinear algebras.
We extend our previous theory of the gauging of classical quadratically nonlinear algebras without a central charge but with a coset structure, to the quantum level. Inserting the minimal anomalies into the classical transformation rules of the currents introduces further quantum corrections to the classical transformation rules of the gauge fields and currents which additively renormalize the ...
