RNA-binding properties of the mitochondrial Y-box protein RBP16.
We have previously identified a mitochondrial Y-box protein in Trypanosoma brucei that we designated RBP16. The predicted RBP16 amino acid sequence revealed the presence of a cold-shock domain at its N-terminus and a glycine- and arginine-rich C-terminus reminiscent of an RGG RNA-binding motif. Since RBP16 is capable of interacting with different guide RNAs (gRNAs) in vitro and in vivo primaril...
متن کاملTrypanosoma brucei RBP16 is a mitochondrial Y-box family protein with guide RNA binding activity.
Trypanosoma brucei mitochondria possess a unique mechanism of mRNA maturation called RNA editing. In this process, uridylate residues are inserted and deleted posttranscriptionally into pre-mRNA to create translatable messages. The genetic information for RNA editing resides in small RNA molecules called guide RNAs (gRNAs). Thus, proteins in direct contact with gRNA are likely to catalyze or in...
متن کاملBinding of Y-box proteins to RNA: involvement of different protein domains.
Eukaryotic Y-box proteins are reported to interact with a wide variety of nucleic acid structures to act as transcription factors and mRNA masking proteins. The modular structure of Y-box proteins includes a highly conserved N-terminal cold-shock domain (CSD, equivalent to the bacterial cold-shock proteins) plus four basic C-terminal domains containing arginine clusters and aromatic residues. I...
متن کاملThe up-regulation of Y-box binding proteins (DNA binding protein A and Y-box binding protein-1) as prognostic markers of hepatocellular carcinoma.
PURPOSE The development of hepatocellular carcinoma is associated with the chronic inflammation of the liver caused by various factors such as hepatitis B or C virus infection. Previously, we reported DNA binding protein A (dbpA) as a candidate molecule that can accelerate inflammation-induced hepatocarcinogenesis. DbpA belongs to the Y-box binding protein family, and Y-box binding protein-1 (Y...
متن کاملRBP16 is a multifunctional gene regulatory protein involved in editing and stabilization of specific mitochondrial mRNAs in Trypanosoma brucei.
RBP16 is a Trypanosoma brucei mitochondrial RNA-binding protein that associates with guide RNAs (gRNAs), mRNAs, and ribosomal RNAs. Based on its inclusion in the multifunctional Y-box protein family and its ability to bind multiple RNA classes, we hypothesized that RBP16 plays a role in diverse aspects of mitochondrial gene regulation. To gain insight into RBP16 function, we generated cells exp...
