SeekRBP: Leveraging Sequence-Structure Integration with Reinforcement Learning for Receptor-Binding Protein Identification

SeekRBP is a novel sequence-structure framework that leverages reinforcement learning and a multi-armed bandit strategy to dynamically optimize negative sampling, thereby overcoming the limitations of traditional methods in accurately identifying receptor-binding proteins despite extreme sequence divergence and class imbalance.

Causal Circuit Tracing Reveals Distinct Computational Architectures in Single-Cell Foundation Models: Inhibitory Dominance, Biological Coherence, and Cross-Model Convergence

This study introduces causal circuit tracing to reveal that distinct single-cell foundation models (Geneformer and scGPT) share conserved computational architectures characterized by inhibitory dominance and biological coherence, with cross-model consensus identifying disease-associated domains that are validated by CRISPRi as reflecting co-expression rather than causal encoding.
