Effects of SUMOylation on the subcellular localization and function of DAXX / 生理学报

ABSTRACT

Death domain-associated protein (DAXX) as a multifunctional nuclear protein widely resides in nucleolus, nucleoplasm, chromatin, promyelocytic leukaemia nuclear bodies (PML-NBs) and cytoplasm. It plays significant roles in transcriptional regulation, apoptosis, cell cycle and other biological activities. Small ubiquitin-like modifier (SUMO) is required for SUMOylation which is a highly conserved post-translational modification in a wide variety of cellular processes. Numerous studies demonstrated that SUMOylation has a great effect on the subcellular localization and functional regulation of DAXX. This review will provide a summary for SUMOylation of DAXX.
