EBNA1 SUMOylation by PIAS1 suppresses EBV lytic replication and enhances episome maintenance [PDF]

open access: yesmBio
Epstein-Barr virus nuclear antigen 1 (EBNA1) is essential for the replication and stable maintenance of the viral episome in infected cells. Here, we identify the SUMO E3 ligase PIAS1 as a key regulator of EBNA1 through site-specific SUMOylation.

APP SUMOylation prevents BACE1 cleavage of APP and increases BACE1 degradation to promote the nonamyloidogenic pathway [PDF]

open access: yesMolecular Medicine
Amyloid precursor protein (APP) plays a key role in the pathogenesis of Alzheimer’s disease (AD). APP undergoes different posttranslational modifications, but the role of SUMOylation modification of APP in the pathogenesis of AD is not known.

SUMOylation Connects Cell Stress Responses and Inflammatory Control: Lessons From the Gut as a Model Organ

open access: yesFrontiers in Immunology, 2021
Conjugation with the small ubiquitin-like modifier (SUMO) constitutes a key post-translational modification regulating the stability, activity, and subcellular localization of its target proteins.

Phosphorylation of Ubc9 by Cdk1 enhances SUMOylation activity. [PDF]

open access: yesPLoS ONE, 2012
Increasing evidence has pointed to an important role of SUMOylation in cell cycle regulation, especially for M phase. In the current studies, we have obtained evidence through in vitro studies that the master M phase regulator CDK1/cyclin B kinase ...

Sumoylation of the human histone H4 tail inhibits p300-mediated transcription by RNA polymerase II in cellular extracts

open access: yeseLife, 2021
The post-translational modification of histones by the small ubiquitin-like modifier (SUMO) protein has been associated with gene regulation, centromeric localization, and double-strand break repair in eukaryotes.

Sumoylation of Hes6 Regulates Protein Degradation and Hes1-Mediated Transcription [PDF]

open access: yesEndocrinology and Metabolism, 2015
BackgroundHes6 is a transcriptional regulator that induces transcriptional activation by binding to transcription repressor Hes1 and suppressing its activity. Hes6 is controlled by the ubiquitin-proteosome-mediated degradation system.

Regulation of Smoothened Trafficking and Abundance in Hedgehog Signaling

open access: yesFrontiers in Cell and Developmental Biology, 2022
The GPCR-family protein Smoothened (Smo) is essential for Hedgehog (Hh) signal transduction in both insects and vertebrates. The regulation of subcellular localization and abundance of Smo is a critical step in Hh signaling.

Analysis of human cytomegalovirus-encoded SUMO targets and temporal regulation of SUMOylation of the immediate-early proteins IE1 and IE2 during infection. [PDF]

open access: yesPLoS ONE, 2014
Post-translational modification of proteins by members of the small ubiquitin-like modifier (SUMO) is involved in diverse cellular functions. Many viral proteins are SUMO targets and also interact with the cellular SUMOylation system.
