Constitutive patterns of gene expression regulated by RNA-binding proteins



RNA-binding proteins regulate a number of cellular processes, including synthesis, folding, translocation, assembly and clearance of RNAs. Recent studies have reported that an unexpectedly large number of proteins are able to interact with RNA, but partners of many RNA-binding proteins are still uncharacterized. 

In a recent publication [1], we combined prediction of ribonucleoprotein interactions, based on catRAPID calculations, with analysis of protein and RNA expression profiles from human tissues. We found strong interaction propensities for both positively- and negatively-correlated expression patterns. Our integration of in silico and ex vivo data unraveled two major types of protein-RNA interactions, with positively-correlated patterns related to cell cycle control and negatively- correlated patterns related to survival, growth and differentiation. 

Our analysis sheds light on the role of RNA-binding proteins in regulating proliferation and differentiation processes, and we provide a data exploration tool to aid the design of future experimental studies.
