Exploring the Protein Sequence Space with Global Generative Models (2305.01941v1)

Abstract: Recent advancements in specialized large-scale architectures for training image and language have profoundly impacted the field of computer vision and NLP. LLMs, such as the recent ChatGPT and GPT4 have demonstrated exceptional capabilities in processing, translating, and generating human languages. These breakthroughs have also been reflected in protein research, leading to the rapid development of numerous new methods in a short time, with unprecedented performance. LLMs, in particular, have seen widespread use in protein research, as they have been utilized to embed proteins, generate novel ones, and predict tertiary structures. In this book chapter, we provide an overview of the use of protein generative models, reviewing 1) LLMs for the design of novel artificial proteins, 2) works that use non-Transformer architectures, and 3) applications in directed evolution approaches.
