RNA-TetherTech: Revolutionizing In Vivo Post-Transcriptional Gene Regulation

The Need

In the field of post-transcriptional gene regulation, understanding the functions of RNA-binding proteins is crucial for controlling cellular processes and development in organisms. However, the lack of reliable tools for studying these proteins in vivo, particularly in plant cells, has hindered progress. Existing techniques are primarily in vitro and involve complex processes like heterologous expression and purification of individual proteins, making them laborious and less effective. The need for a system, method, and technique that allows for the modulation and study of post-transcriptional RNA regulation is evident.

The Technology

Our innovative technology addresses this gap with an expression construct designed for expressing an engineered protein capable of tethering a protein of interest to a target RNA molecule. This construct comprises a promoter linked to a nucleic acid sequence encoding the engineered protein. The RNA-binding polypeptide of the engineered protein, containing various RNA-binding structural motifs, recognizes and specifically binds to an RNA recognition sequence in the target RNA molecule, thereby facilitating the tethering of the protein of interest.
