Gene Information

human immunodeficiency virus 1 ... gag(155030)

General description

Contains amino acid residues [77-436] of HIV-1 gag antigen.
The human immunodeficiency virus 1 (HIV−1) gag antigen is a recombinant 39 kDa protein encoded by the GAG gene of the human immunodeficiency virus (HIV) type I expressed in and isolated from Escherichia coli. It has a β−galactosidase tag (114 kDa) on the N−terminus. HIV-1 Gag exists as monomers or lower-order oligomers in the cytosol. At the plasma membrane, it forms higher-order multimers.

Application

HIV-1 gag has been used in the coculture with an autologous cluster of differentiation T (CD4+ T) to study the ability of monocyte-derived dendritic cells (MDC1) to induce human immunodeficiency virus 1 (HIV−1) latency reversal (LR).

Biochem/physiol Actions

The human immunodeficiency virus 1 (HIV−1) gag (p24) antigen reacts strongly with HIV positive serum and may be used as a positive control for evaluating antibodies to HIV. At transcription sites, HIV-1 Gag creates ribonucleoprotein complexes with unspliced viral RNA. The HIV-1 Gag protein is accountable for packaging genomic RNA (gRNA) and the assembly of immature viral particles.
Positive control for HIV antibodies.

The HIV-1 Gag protein is responsible for genomic RNA (gRNA) packaging and immature viral particle assembly. Although the presence of gRNA in virions is required for viral infectivity, in its absence, Gag can assemble around cellular RNAs and form particles
