The complex life of RNA
This EMBO and EMBL symposium convenes leaders, postdoctoral researchers, and students to discuss current RNA biology. The programme spans transcription, RNA processing and modification, messenger-RNA export and localisation, RNA surveillance and decay, translation, non-coding RNAs, gene-expression control, and coupling among these processes.
Chemical biology 2026
This EMBO workshop covers emerging chemical-biology research spanning computational protein design, big data and AI, technologies for probing and manipulating biology, chemical synthetic biology, and RNA.
Towards a More Authentic Vision of the (multi)Coding Potential of RNA
Ten of thousands of open reading frames (ORFs) are hidden within transcripts. They have eluded annotations because they are either small or within unsuspected locations. These are named alternative ORFs (altORFs) or small ORFs and have recently been highlighted by innovative proteogenomic approaches, such as our OpenProt resource, revealing their existence and implications in biological functions. Due to the absence of altORFs from annotations, pathogenic mutations within these are being ignored. I will discuss our latest progress on the re-analysis of large-scale proteomics datasets to improve our knowledge of proteomic diversity, and the functional characterization of a second protein coded by the FUS gene. Finally, I will explain the need to map the coding potential of the transcriptome using artificial intelligence rather than with conventional annotations that do not capture the full translational activity of ribosomes.
RNA-driven phase separation from cells to SARS
Biomolecular condensation is a mechanism for controlling cell organization. Many condensates are rich in nuclei acids such as RNA. The role of specific RNA sequences and structures in promoting the molecular identity of condensates formed for cell polarity and division and by the SARS CoV-2 virus will be discussed.
Virus-like intercellular communication in the nervous system
The neuronal gene Arc is essential for long-lasting information storage in the mammalian brain and mediates various forms of synaptic plasticity. We recently discovered that Arc self-assembles into virus-like capsids that encapsulate RNA. Endogenous Arc protein is released from neurons in extracellular vesicles that mediate the transfer of Arc mRNA into new target cells. Evolutionary analysis indicates that Arc is derived from a vertebrate lineage of Ty3/gypsy retrotransposons, which are also ancestral to retroviruses such as HIV. These findings suggest that Gag retroelements have been repurposed during evolution to mediate intercellular communication in the nervous system that may underlie cognition and memory.
