arXiv:2606.16044v1 Announce Type: new Abstract: Protein language models (pLMs) can generate novel protein sequences with properties beyond those observed in nature, yet the mechanisms underlying protein generation remain poorly understood. Existing mechanistic interpretability methods based on sparse autoencoders and transcoders primarily focus on protein representation learning models and do not capture the computation required for autoregressive generation. Here, we introduce ProGenMech, a mechanistic interpretability framework for generative protein language models that extends cross-layer
The increasing sophistication and widespread use of protein language models for generating novel proteins necessitate a deeper understanding of their underlying mechanisms.
Understanding how generative protein language models function will accelerate the design and optimization of synthetic proteins for various applications, impacting therapeutics, materials, and potentially energy.
The introduction of ProGenMech provides a dedicated framework for mechanistic interpretability in generative protein language models, moving beyond representation learning models.
