Cytoplasmic Dynein Promotes HIV-1 Uncoating
Retroviral capsid (CA) cores undergo uncoating during their retrograde transport (toward the nucleus), and/or after reaching the nuclear membrane. However, whether HIV-1 CA core uncoating is dependent upon its transport is not understood. There is some evidence that HIV-1 cores retrograde transport involves cytoplasmic dynein complexes translocating on microtubules. Here we investigate the role...
متن کاملEarly cytoplasmic uncoating is associated with infectivity of HIV-1.
After fusion, HIV delivers its conical capsid into the cytoplasm. To release the contained reverse-transcribing viral genome, the capsid must disassemble in a process termed uncoating. Defining the kinetics, dynamics, and cellular location of uncoating of virions leading to infection has been confounded by defective, noninfectious particles and the stochastic minefield blocking access to host D...
متن کاملRaman spectroscopic signatures of echovirus 1 uncoating.
UNLABELLED In recent decades, Raman spectroscopy has entered the biological and medical fields. It enables nondestructive analysis of structural details at the molecular level and has been used to study viruses and their constituents. Here, we used Raman spectroscopy to study echovirus 1 (EV1), a small, nonenveloped human pathogen, in two different uncoating states induced by heat treatments. R...
متن کاملDistinct functions of diaphanous-related formins regulate HIV-1 uncoating and transport.
Diaphanous (Dia)-related formins (DRFs) coordinate cytoskeletal remodeling by controlling actin nucleation and microtubule (MT) stabilization to facilitate processes such as cell polarization and migration; yet the full extent of their activities remains unknown. Here, we uncover two discrete roles and functions of DRFs during early human immunodeficiency virus type 1 (HIV-1) infection. Indepen...
متن کاملHIV-1 DNA Flap formation promotes uncoating of the pre-integration complex at the nuclear pore.
The HIV-1 central DNA Flap acts as a cis-acting determinant of HIV-1 genome nuclear import. Indeed, DNA-Flap re-insertion within lentiviral-derived gene transfer vectors strongly stimulates gene transfer efficiencies. In this study, we sought to understand the mechanisms by which the central DNA Flap mediates HIV-1 nuclear import. Here, we show that reverse transcription (RT degrees) occurs wit...
