Elements in the long terminal repeat of HIV-1 that interact with nuclear extracts from Jurkat cells persistently infected with vaccinia virus.
Previous reports showed transactivation of the long terminal repeat (LTR) of HIV-1 in Jurkat cells persistently infected with vaccinia virus. In this communication, electrophoretic mobility shift assays were used to characterize the elements in HIV-1 LTR which might be responsible for the mechanism of transactivation. The results indicated that two elements, those for binding NF-kB and NFAT-1, were able to interact with nuclear extracts derived from Jurkat cells persistently infected with vaccinia virus, suggesting that they may play a role in the transactivation of HIV-1 LTR.
