ABSTRACTA considerable amount of smooth muscle phenotypic diversity is generated by tissue-specific and developmentally regulated splicing of alternative exons. The control mechanisms are unknown. We are using a myosin phosphatase targeting subunit-1 (MYPT1) alternative exon as a model to investigate this question. In the present study, we show that the RNA binding proteins TIA and PTB function as antagonistic enhancers and suppressors of splicing of the alternative exon, respectively. Each functions through …
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 on Drug Abuse of the National Institutes of Health.
