Human immunodeficiency virus type 1 (HIV-1) gene expression is activated by Tat, a virally
encoded protein. Tat trans-activation requires viral (trans-activation—responsive; TAR) RNA
sequences located in the R region of the long terminal repeat (LTR). Existing evidence
suggests that Tat probably cooperates with cellular factors that bind to TAR RNA in the
overall trans-activation process. A HeLa complementary DNA was isolated and
characterized that encodes a TAR RNA-binding protein (TRBP). TRBP activated the HIV-1 …
Human immunodeficiency virus type 1 (HIV-1) gene expression is activated by Tat, a virally encoded protein. Tat trans-activation requires viral (trans-activation—responsive; TAR) RNA sequences located in the R region of the long terminal repeat (LTR). Existing evidence suggests that Tat probably cooperates with cellular factors that bind to TAR RNA in the overall trans-activation process. A HeLa complementary DNA was isolated and characterized that encodes a TAR RNA-binding protein (TRBP). TRBP activated the HIV-1 LTR and was synergistic with Tat function.
