New hypothesis and search method improve protein evolution with language models

Researchers have introduced a new hypothesis called the Linear Fitness Subspace (LFS), which suggests that a small set of directions within protein language models (PLMs) can accurately predict fitness variations for proteins. This observation is based on the idea that representation changes in PLMs due to mutations are linearly accessible from a few labeled variants. To leverage this, they developed Subspace-Guided Evolutionary Search (SGES), a method that estimates an LFS from a small sample to improve surrogate modeling and uncertainty estimation within this learned subspace. SGES has demonstrated improved fitness prediction and search efficiency across numerous protein assays compared to existing methods. AI

IMPACT This research could lead to more efficient and accurate methods for protein design and engineering by improving how protein language models are utilized.
