Abstract 3197: RNase-L modulates transcriptional and post-transcriptional responses to mitogenic stimuli through serum response factor and tristetraprolin.
Abstract:RNase-L is an endoribonuclease that functions in a range of important physiologic activities including the innate immune response and control of cell proliferation and is dysregulated in pathologic conditions including cancer. RNase-L is tightly regulated and requires the binding of 2’,5’-linked oligoadenylates (2-5A: px5′A(2′p5′A)n; x=1-2;n>2) to induce oligomerization and enzymatic activity. Activated RNase-L cleaves single-stranded regions of cellular and pathogen RNAs, and distinct profiles of RNA a… Show more
scite is a Brooklyn-based organization 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 and 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.
