Allosteric Degradation of XPO1 by SINEs: Mechanistic Insight
2026-05-13
Wing et al. (2025) uncover a new allosteric mechanism by which SINE compounds induce the degradation of exportin 1 (XPO1), a key nuclear export receptor. Their cryo-EM and biochemical studies reveal that SINEs expose a cryptic ASB8 binding site on XPO1, thereby engaging the Cullin–RING E3 ligase pathway for targeted ubiquitination and degradation, extending the conceptual framework of targeted protein degradation.
