Extracellular circulating Tat can be endocytosed by surrounding uninfected cells via the binding to several surface receptors such as CD26, CXCR4, heparan sulfate proteoglycans (HSPG) or LDLR. Neurons are rarely infected, but they internalize Tat via their LDLR. Through its interaction with nuclear HATs, Tat is potentially able to control the acetylation-dependent cellular gene expression. Modulates the expression of many cellular genes involved in cell survival, proliferation or in coding for cytokines or cytokine receptors. Tat plays a role in T-cell and neurons apoptosis. Tat induced neurotoxicity and apoptosis probably contribute to neuroAIDS. Circulating Tat also acts as a chemokine-like and/or growth factor-like molecule that binds to specific receptors on the surface of the cells, affecting many cellular pathways. In the vascular system, Tat binds to ITGAV/ITGB3 and ITGA5/ITGB1 integrins dimers at the surface of endothelial cells and competes with bFGF for heparin-binding sites, leading to an excess of soluble bFGF.

UniRule annotation

Nuclear transcriptional activator of viral gene expression, that is essential for viral transcription from the LTR promoter and replication. Acts as a sequence-specific molecular adapter, directing components of the cellular transcription machinery to the viral RNA to promote processive transcription elongation by the RNA polymerase II (RNA pol II) complex, thereby increasing the level of full-length transcripts. In the absence of Tat, the RNA Pol II generates short or non-processive transcripts that terminate at approximately 60 bp from the initiation site. Tat associates with the CCNT1/cyclin-T1 component of the P-TEFb complex (CDK9 and CCNT1), which promotes RNA chain elongation. This binding increases Tat's affinity for a hairpin structure at the 5'-end of all nascent viral mRNAs referred to as the transactivation responsive RNA element (TAR RNA) and allows Tat/P-TEFb complex to bind cooperatively to TAR RNA. The CDK9 component of P-TEFb and other Tat-activated kinases hyperphosphorylate the C-terminus of RNA Pol II that becomes stabilized and much more processive. Other factors such as HTATSF1/Tat-SF1, SUPT5H/SPT5, and HTATIP2 are also important for Tat's function. Besides its effect on RNA Pol II processivity, Tat induces chromatin remodeling of proviral genes by recruiting the histone acetyltransferases (HATs) CREBBP, EP300 and PCAF to the chromatin. This also contributes to the increase in proviral transcription rate, especially when the provirus integrates in transcriptionally silent region of the host genome. To ensure maximal activation of the LTR, Tat mediates nuclear translocation of NF-kappa-B by interacting with host RELA. Through its interaction with host TBP, Tat may also modulate transcription initiation. Tat can reactivate a latently infected cell by penetrating in it and transactivating its LTR promoter. In the cytoplasm, Tat is thought to act as a translational activator of HIV-1 mRNAs.

UniRule annotation

Miscellaneous

HIV-1 lineages are divided in three main groups, M (for Major), O (for Outlier), and N (for New, or Non-M, Non-O). The vast majority of strains found worldwide belong to the group M. Group O seems to be endemic to and largely confined to Cameroon and neighboring countries in West Central Africa, where these viruses represent a small minority of HIV-1 strains. The group N is represented by a limited number of isolates from Cameroonian persons. The group M is further subdivided in 9 clades or subtypes (A to D, F to H, J and K).UniRule annotation

  • Secreted UniRule annotation
    • Note: Probably localizes to both nuclear and nucleolar compartments. Nuclear localization is mediated through the interaction of the nuclear localization signal with importin KPNB1. Secretion occurs through a Golgi-independent pathway. Tat is released from infected cells to the extracellular space where it remains associated to the cell membrane, or is secreted into the cerebrospinal fluid and sera. Extracellular Tat can be endocytosed by surrounding uninfected cells via binding to several receptors depending on the cell type.UniRule annotation

Acetylation by EP300, CREBBP, GCN5L2/GCN5 and PCAF regulates the transactivation activity of Tat. EP300-mediated acetylation of Lys-50 promotes dissociation of Tat from the TAR RNA through the competitive binding to PCAF's bromodomain. In addition, the non-acetylated Tat's N-terminus can also interact with PCAF. PCAF-mediated acetylation of Lys-28 enhances Tat's binding to CCNT1. Lys-50 is deacetylated by SIRT1.UniRule annotation
Asymmetrical arginine methylation by host PRMT6 seems to diminish the transactivation capacity of Tat and affects the interaction with host CCNT1.UniRule annotation
Phosphorylated by EIF2AK2 on serine and threonine residues adjacent to the basic region important for TAR RNA binding and function. Phosphorylation of Tat by EIF2AK2 is dependent on the prior activation of EIF2AK2 by dsRNA.UniRule annotation
Polyubiquitination by host MDM2 does not target Tat to degradation, but activates its transactivation function and fosters interaction with CCNT1 and TAR RNA.UniRule annotation
