Researchers Unveil Comprehensive Resource for RNA-Binding Protein Motifs Across Eukaryotes

Strategic Insights -

Researchers from the University of Toronto have created a comprehensive resource for RNA-binding protein motifs across eukaryotes, expanding the current repertoire of motifs by four times. The resource, called Eukaryotic Protein-RNA Interactions (EuPRI), includes in vitro binding data for 504 RNA-binding proteins (RBPs) and thousands of predicted motifs. This breakthrough is expected to advance our understanding of post-transcriptional regulation and gene expression in various eukaryotic species.

Key Takeaways:

  • EuPRI is a freely available resource of RNA motifs for 34,746 RBPs from 690 eukaryotes.
  • The resource includes in vitro binding data for 504 RBPs and thousands of predicted motifs.
  • EuPRI quadruples the number of available RBP motifs, expanding the motif repertoire across all major eukaryotic clades.
  • The utility of EuPRI for inferring post-transcriptional function and evolutionary relationships was demonstrated by identifying rapid, recent evolution of post-transcriptional regulatory networks in worms and plants.
  • The research was supported by the U.S. Department of Health & Human Services, the Canadian Institutes of Health Research, and the Cincinnati Children's Hospital Medical Center.
  • The resource was created using an algorithm called Joint Protein-Ligand Embedding, which can detect distant homology relationships and map specificity-determining peptides.

Statistics:

  • EuPRI includes data for 34,746 RBPs from 690 eukaryotes.
  • The resource includes in vitro binding data for 504 RBPs.
  • The predicted motifs in EuPRI are thousands.
  • The resource expands the motif repertoire across all major eukaryotic clades.
  • The research was supported by the U.S. Department of Health & Human Services, which provided $[amount] in funding.
