Since the 1960s, the genetic code has been used to predict protein sequences from DNA and mRNA sequences. Our @nature.com article demonstrates that these predictions miss thousands of protein sequences present in human tissues. www.nature.com/articles/s41... 1/

Our paper, “Deep learning reveals antimicrobial peptides within prions,” is now published in Nature Microbiology @natureportfolio.nature.com. We used AI to ask an unexpected question: could proteins best known for their role in fatal neurodegenerative diseases encode molecules that fight infection?
