Function

[TRA2B_HUMAN] Sequence-specific RNA-binding protein which participates in the control of pre-mRNA splicing. Can either activate or suppress exon inclusion. Acts additively with RBMX to promote exon 7 inclusion of the survival motor neuron SMN2. Activates the splicing of MAPT/Tau exon 10. Alters pre-mRNA splicing patterns by antagonizing the effects of splicing regulators, like RBMX. Binds to the AG-rich SE2 domain in the SMN exon 7 RNA. Binds to pre-mRNA.^[1] ^[2] ^[3] ^[4]

Publication Abstract from PubMed

Tra2-beta1 is a unique splicing factor as its single RNA recognition motif (RRM) is located between two RS (arginine-serine) domains. To understand how this protein recognizes its RNA target, we solved the structure of Tra2-beta1 RRM in complex with RNA. The central 5'-AGAA-3' motif is specifically recognized by residues from the beta-sheet of the RRM and by residues from both extremities flanking the RRM. The structure suggests that RNA binding by Tra2-beta1 induces positioning of the two RS domains relative to one another. By testing the effect of Tra2-beta1 and RNA mutations on the splicing of SMN2 exon 7, we validated the importance of the RNA-protein contacts observed in the structure for the function of Tra2-beta1 and determined the functional sequence of Tra2-beta1 in SMN2 exon 7. Finally, we propose a model for the assembly of multiple RNA binding proteins on this exon.
