PRMT2 promotes HIV-1 latency by preventing nucleolar exit and phase separation of Tat into the Super Elongation Complex [PDF]

open access: yesNature Communications, 2023
The HIV-1 Tat protein hijacks the Super Elongation Complex (SEC) to stimulate viral transcription and replication. However, the mechanisms underlying Tat activation and inactivation, which mediate HIV-1 productive and latent infection, respectively ...

Penetratin-membrane association: W48/R52/W56 shield the peptide from the aqueous phase. [PDF]

open access: yesBiophysical Journal, 2005
Using molecular dynamics simulations, we studied the mode of association of the cell-penetrating peptide penetratin with both a neutral and a charged bilayer. The results show that the initial peptide-lipid association is a fast process driven by electrostatic interactions.

Superior HIV‐1 TAR Binders with Conformationally Constrained R52 Arginine Mimics in the Tat(48–57) Peptide

open access: yesChemMedChem, 2018
AbstractWe report a 100‐fold increase in binding affinity of the Tat(48–57) peptide to HIV‐1 transcriptional activator‐responsive element (TAR) RNA by replacing Arg52, an essential and critical residue for Tat's specific binding, with (2S,4S)‐4‐guanidinoproline.
