TLDR
A review of recent biochemical and structural studies that help clarify the mechanisms of viral assembly, infection, and replication of human immunodeficiency virus type 1.
Abstract
Human immunodeficiency virus type 1 is a complex retrovirus encoding 15 distinct proteins. Substantial progress has been made toward understanding the function of each protein, and three-dimensional structures of many components, including portions of the RNA genome, have been determined. This review describes the function of each component in the context of the viral life cycle: the Gag and Env structural proteins MA (matrix), CA (capsid), NC (nucleocapsid), p6, SU (surface), and TM (transmembrane); the Pol enzymes PR (protease), RT (reverse transcriptase), and IN (integrase); the gene regulatory proteins Tat and Rev; and the accessory proteins Nef, Vif, Vpr, and Vpu. The review highlights recent biochemical and structural studies that help clarify the mechanisms of viral assembly, infection, and replication.

Matrix Proteoglycans: From Molecular Design to Cellular Function

TL;DR: The proteoglycan superfamily now contains more than 30 full-time molecules that fulfill a variety of biological functions and additional roles, derived from studies of mutant animals, indicate that certain proteoglycans are essential to life whereas others might be redundant.

Identification of Host Proteins Required for HIV Infection Through a Functional Genomic Screen

TL;DR: This article performed a large-scale small interfering RNA screen to identify host factors required by HIV-1 and identified more than 250 HIV-dependency factors (HDFs), which participate in a broad array of cellular functions and implicate new pathways in the viral life cycle.

Identification of host proteins required for HIV infection through a functional genomic screen

TL;DR: A large-scale small interfering RNA screen was performed to identify host factors required by HIV-1 and more than 250 HIV-dependency factors (HDFs) were identified, suggesting that viruses evolve in host cells that optimally perform the functions required for their life cycle.

Architecture and secondary structure of an entire HIV-1 RNA genome

TL;DR: The structure of an entire HIV-1 genome at single nucleotide resolution is reported using SHAPE, a high-throughput RNA analysis technology and indicates that extensive RNA structure constitutes an important component of the genetic code.

MOLSCRIPT: a program to produce both detailed and schematic plots of protein structures

TL;DR: The MOLSCRIPT program as discussed by the authors produces plots of protein structures using several different kinds of representations, including simple wire models, ball-and-stick models, CPK models and text labels.

The β-Chemokine Receptors CCR3 and CCR5 Facilitate Infection by Primary HIV-1 Isolates

TL;DR: The ability of various members of the chemokine receptor family to support the early stages of HIV-1 infection helps to explain viral tropism and beta-chemokine inhibition of primary HIV- 1 isolates.

Core structure of GP41 from the HIV envelope glycoprotein

TL;DR: The crystal structure of this complex, composed of the peptides N36 and C34, is a six-helical bundle that shows striking similarity to the low-pH-induced conformation of influenza hemagglutinin and likely represents the core of fusion-active gp41.

The lymphocyte chemoattractant SDF-1 is a ligand for LESTR/fusin and blocks HIV-1 entry.

TL;DR: Testing of potential receptors demonstrated that SDF-1 signalled through, and hence 'adopted', the orphan receptor LESTR, which is therefore designated CXC-chemokine receptor-4 (CXCR-4).

Crystal structure at 3.5 A resolution of HIV-1 reverse transcriptase complexed with an inhibitor.

TL;DR: A 3.5 angstrom resolution electron density map of the HIV-1 reverse transcriptase heterodimer complexed with nevirapine, a drug with potential for treatment of AIDS, reveals an asymmetric dimer.
