The RNA Biology (ptRNA) thematic group aims to promote synergies and stimulate the exchange of ideas between different scientists working in Portugal in the different areas of RNA, including RNA processing, RNA modifications, RNA stability and decay, Non-coding RNAs, tRNA biology, role of RNA in regulating gene expression in health and disease. We also intend to promote scientific meetings of RNA enthusiasts, known as ptRNA meetings, where the latest developments and cutting-edge technologies in the field of RNA are discussed.
