STUB1-TPIT Axis Controls ACTH Secretion in Cushing Disease
2026-07-28
Liu et al. (2025) reveal that the E3 ligase STUB1 targets the transcription factor TPIT for ubiquitin-mediated degradation, suppressing pro-opiomelanocortin (POMC) expression and ACTH secretion in Cushing disease models. Their findings identify the STUB1-TPIT complex as a potential therapeutic target and provide a mechanistic basis for drug screening to modulate ACTH-driven endocrine disorders.
