Abstract:We examined the regulatory mechanisms of binding and transcriptional enhancement of the 21-bp core element of the enhancer of human T-cell leukemia virus type I (HTLV-I) in response to forskolin, 12-0-tetradecanoylphorbol-13-acetate (TPA), and a viral transactivator, p4laX. The 21-bp core element has been shown to bind to a cyclic AMP-responsive element binding protein (CREB)-like molecule at the site of an imperfect palindrome containing the TGAC motif. Experiments with oligonucleotides with mutations in the … Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
