Trans-activator of transcription (TAT) is a key protein from simian immunodeficiency virus (SIV). SIVs are retroviruses which cause often non-pathogenic infections of members of the simian species (monkey). Human immunodeficiency virus strains (HIV) developed from the SIV's. During HIV infection a small amount of TAT protein is produced early on which binds to an RNA stem-loop structure, the trans-activating response element (TAR), located at the 5' ends of HIV-1 transcripts, this binding results in increased production of full-length viral RNA. This positive feedback loop allows HIV to have an explosive response once a threshold level of TAT is produced, helping it defeat the bodies immune response. TAT protein also associates with RNA polymerase II complexes during early transcription elongation. TAT is also released into the host bloodstream where it can be absorbed by neighbouring, uninfected cells. TAT is toxic to these cells and induces apoptosis and inhibition of T-cell proliferation, thus assisting in the progression toward AIDS. Thus, TAT appears to be involved in both host immune suppression and viral dissemination.TAT is being investigated as a therapeutic target and as an agent to be used in a potential HIV vaccine.
