An HIV protein that helps produce new complete HIV RNA genomes, and ultimately new virus, from the HIV proviral DNA template present in infected cells Tat may also be involved in: 1) the reactivation of other latent viruses in people with AIDS, such as JC virus, the cause of PML; 2) the development of AIDS-related KS by stimulating the formation of new blood vessels; and 3) the triggering of anergy and apoptosis in CD4 cells
An HIV gene that is essential in the formation of new virus particles The tat gene codes for the production of the "tat protein" which undertakes this function The tat protein may also result in reactivation of other viruses, stimulate the formation of Kaposi's sarcoma cells, and accelerate human cell death and immune unresponsiveness
