Post‐Translational Modifications of TOE3 Regulate Antiviral Defense in Tobacco

Advanced Science, EarlyView.
CK2αL phosphorylates TOE3 and enhances its stability, while FBXL1 promotes the ubiquitination‐degradation of TOE3 via the 26S proteasome. Compared to CK2αL‐phosphorylated TOE3, nonphosphorylated TOE3 shows a much higher affinity for FBXL1 and is more susceptible to ubiquitination‐degradation, thus facilitating viral infection. The regulatory mechanisms

SUMOylation is essential for Sirt2 tumor-suppressor function in neuroblastoma

Neoplasia: An International Journal for Oncology Research, 2021
SUMOylation is an important post-translational modification that participates in a variety of cellular physiological and pathological processes in eukaryotic cells. Sirt2, a NAD+-dependent deacetylase, usually exerts a tumor-suppressor function. However,

The role of SUMOylation during development

Biochemical Society Transactions, 2020
During the development of multicellular organisms, transcriptional regulation plays an important role in the control of cell growth, differentiation and morphogenesis. SUMOylation is a reversible post-translational process involved in transcriptional regulation through the modification of transcription factors and through chromatin remodelling (either ...

METTL10‐Mediated PIAS3 Methylation Links Purine Metabolism to Gastric Cancer Progression

Advanced Science, EarlyView.
METTL10‐mediated methylation of PIAS3 at K442 inhibits its SUMO E3 ligase activity toward MITF. This reduces MITF SUMOylation and subsequent RNF4‐mediated ubiquitination, leading to MITF protein accumulation and gastric cancer progression. Abstract Metabolic dysregulation plays a significant role in the development of gastric cancer (GC).

SUMOylation inTrypanosoma brucei

PeerJ, 2013
Small ubiquitin like modifier (SUMO) proteins are involved in many processes in eukaryotes. We here show that Trypanosoma brucei SUMO (Tb927.5.3210) modifies many proteins. The levels of SUMOylation were unaffected by temperature changes but were increased by severe oxidative stress.

A SUMOylation wave to anchor the genome [PDF]

Journal of Cell Biology, 2021
Chromatin tethers to the nuclear envelope are lost during mitosis to facilitate chromosome segregation. How these connections are reestablished to ensure functional genome organization in interphase is unclear. Ptak et al. (2021. J. Cell Biol.https://doi.org/10.1083/jcb.202103036) identify a phosphorylation and SUMOylation-dependent cascade that links ...

Hypoxia‐Induced PRMT1 Lactylation Drives Vimentin Arginine Asymmetric Dimethylation in Tumor Metastasis

Advanced Science, EarlyView.
Hypoxia triggers lactylation of PRMT1 at K134/K145, enhancing its methyltransferase activity to asymmetrically dimethylate vimentin R64. This post‐translational cascade promotes vimentin filament assembly, cytoskeletal remodeling, and tumor metastasis, with PRMT1 inhibition (MS023) reducing metastatic colonization.

SUMOylation and deSUMOylation at a glance

Journal of Cell Science, 2009
Small ubiquitin-related modifiers (SUMOs) are ubiquitin-like polypeptides that become covalently conjugated to cellular proteins in a manner similar to ubiquitylation ([Johnson, 2004][1]).

CSN6 Promotes Pancreatic Cancer Progression and Gemcitabine Resistance via Antagonizing DCAF1‐Mediated Ubiquitination of NPM1

Advanced Science, EarlyView.
COP9 signalosome subunit 6 (CSN6) promotes the auto‐ubiquitination and degradation of DDB1‐CUL4 associated factor 1 (DCAF1), thereby antagonizing DCAF1‐mediated ubiquitination of Nucleophosmin (NPM1). This stabilization of NPM1 enhances the ribosome biogenesis process and the translation of specific gemcitabine‐resistance proteins, ultimately driving ...
