Widespread variation in molecular interactions and regulatory properties among transcription factor isoforms
Lambourne, Mattioli, Santoso, et al. compare protein isoforms of the same transcription factor genes through high-throughput profiling of DNA-binding, protein-binding, activation, localization, and condensate formation. Differences between isoforms are widespread, often unpredictable from sequence differences, and inform a disease-associated categorization of alternative isoforms into rewirers or negative regulators.
