Lack of NFATc1 SUMOylation prevents autoimmunity and alloreactivity

2020

A novel transgenic mouse, in which the transcription factor NFATc1 bears lysine-to-arginine mutations that prevent modification by SUMO, develops normally and is healthy. However, SUMO-insensitive NFATc1 transmits strong tolerogenic signals, thus preventing autoimmune and alloimmune T cell responses.

Heat shock protein 27 is involved in SUMO-2/3 modification of heat shock factor 1 and thereby modulates the transcription factor activity

2009

Heat shock protein 27 (HSP27) accumulates in stressed cells and helps them to survive adverse conditions. We have already shown that HSP27 has a function in the ubiquitination process that is modulated by its oligomerization/phosphorylation status. Here, we show that HSP27 is also involved in protein sumoylation, a ubiquitination-related process. HSP27 increases the number of cell proteins modified by small ubiquitin-like modifier (SUMO)-2/3 but this effect shows some selectivity as it neither affects all proteins nor concerns SUMO-1. Moreover, no such alteration in SUMO-2/3 conjugation is achievable by another HSP, such as HSP70. Heat shock factor 1 (HSF1), a transcription factor responsib…
