Tat
|
tat
|
HIV-1 Tat upregulates the total levels of PP2A protein and downregulates the inactive form of phosphorylated PP2A, which leads to inhibit hTERT activity directly or indirectly in CD4+ T cells |

|
tat
|
Protein phosphatase-2A (PP2A) and protein phosphatase-1 (PP1) regulate HIV-1 Tat-activated transcription through dephosphorylation of CDK9 |
PubMed
|
|
tat
|
HIV-1 Tat associates with the promoters of both PPP2R1B and PPP2R5E to increase PPP2R1B and PPP2R5E RNA and protein levels as well as PP2A activity in Jurkat T cells |
PubMed
|
|
tat
|
An increase in the amount of PP2A core enzyme with a concomitant decrease in the amount of PP2A holoenzyme inhibits HIV-1 Tat-stimulated transcription from the HIV-1 LTR promoter, indicating a role for PP2A in the modulation of HIV-1 gene expression |

Vpr
|
vpr
|
Amino-acid peptide sequence (residues 77-92) of HIV-1 Vpr binds to PP2A1. The sequence from HIV-1 89.6 strain is a cell penetrating and death domain |

vpr
|
HIV-1 Vpr was found to upregulate PP2A in fission yeast |
PubMed

|
vpr
|
HIV-1 Vpr forms a complex with HIV-1 nucleocapsid that directly activates PP2A |
PubMed

Vpu
|
vpu
|
HIV-1 Vpu is identified to have a physical interaction with protein phosphatase 2, regulatory subunit B', epsilon isoform (PPP2R5E) in human HEK293 and/or Jurkat cell lines by using affinity tagging and purification mass spectrometry analyses |
