{"doi":"10.1261/rna.079605.123","title":"Small-molecule Ro-08-2750 interacts with many RNA-binding proteins and elicits MUSASHI2-independent phenotypes","abstract":"RNA-binding proteins (RBPs) are key regulators of gene expression. Small molecules targeting these RBP-RNA interactions are a rapidly emerging class of therapeutics for treating a variety of diseases. Ro-08-2750 (Ro) is a small molecule identified as a competitive inhibitor of Musashi (MSI)-RNA interactions. Here, we show that multiple Ro-dependent cellular phenotypes, specifically adrenocortical steroid production and cell viability, are Musashi-2 (MSI2)-independent. Using an unbiased proteome-wide approach, we discovered Ro broadly interacts with RBPs, many containing RRM domains. To confirm this finding, we leveraged the large-scale ENCODE data to identify a subset of RBPs whose depletion phenocopies Ro inhibition, indicating Ro is a promiscuous inhibitor of multiple RBPs. Consistent with broad disruption of ribonucleoprotein complexes, Ro treatment leads to stress granule formation. This strategy represents a generalizable framework for validating the specificity and identifying targets of RBP inhibitors in a cellular context.","journal":"RNA","year":2023,"id":371324,"datarank":0.3572698224825066,"base_score":1.9459101490553132,"endowment":1.9459101490553132,"self_citation_contribution":0.29188652235829704,"citation_network_contribution":0.06538330012420958,"self_endowment_contribution":0.29188652235829704,"citer_contribution":0.06538330012420958,"corpus_percentile":null,"corpus_rank":null,"citation_count":6,"citer_count":6,"citers_with_citation_signal":5,"citers_with_endowment":5,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9598,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1007717,"name":"Marcin Piotr Sajek","orcid":"0000-0002-4115-4191","position":1,"is_corresponding":false},{"id":761144,"name":"Elisabeth Murphy","orcid":"0009-0006-2588-1985","position":2,"is_corresponding":false},{"id":297836,"name":"Aaron Issaian","orcid":"0000-0001-9762-5098","position":3,"is_corresponding":false},{"id":761143,"name":"Amber Baldwin","orcid":"0000-0002-7346-3052","position":4,"is_corresponding":false},{"id":1008132,"name":"Evan Harrison","orcid":null,"position":5,"is_corresponding":false},{"id":1007718,"name":"Miles E.
