Researchers have used artificial intelligence and evolutionary biology to develop a novel fluorescent protein, esmGFP, through their advanced AI model, ESM3.
ESM3, trained on a vast dataset of protein sequences, structures, and annotations, simulated 500 million years of molecular evolution to design esmGFP.
Despite sharing only 58% sequence similarity with its closest natural counterpart, esmGFP exhibited fluorescence in laboratory tests, showcasing the model's ability to create functional proteins not found in nature.
This breakthrough has significant implications for applications like drug discovery, environmental monitoring, and synthetic biology, offering new possibilities for developing enzymes, therapeutics, and tools for protein evolution exploration.
