Scientists are exploring parts of the human genome that were previously overlooked, focusing on non-canonical open reading frames (ncORFs) that may produce small proteins called microproteins. These microproteins could play significant roles in human health and disease. The TransCODE Consortium has found that about 25% of these ncORFs produce detectable peptides, suggesting they are more common than previously thought. This discovery could impact our understanding of diseases and lead to new medical treatments. The research also introduces a new concept called “peptideins,” which are microproteins with potential functions. By studying these, scientists hope to uncover new insights into the human proteome, which could revolutionize biomedical science and drug development.
