Abstract:Regulatory elements interacting with DNA-binding proteins have been investigated in the promoter sequence of the early PE38 gene in the Autographa californica nuclear polyhedrosis virus (AcNPV). A GATA motif located 50 nucleotides upstream of the PE38 transcriptional start site is recognized differentially in the course of infection. As demonstrated by footprint and gel mobility shift assays, the GATA sequences TTATCT are protected by nuclear extracts from uninfected Spodoptera frugiperda cells and from S. fru…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
