Web8 de jan. de 2016 · Abstract. SUMOylation is a ubiquitin-related transient posttranslational modification pathway catalyzing the conjugation of small ubiquitin-like modifier (SUMO) proteins (SUMO1, SUMO2, and SUMO3) to lysine residues of proteins. SUMOylation targets a wide variety of cellular regulators and thereby affects a multitude of different cellular … Web20 de jun. de 2024 · Interestingly, some HIF hydroxylases can also regulate metabolic processes through mechanisms that are at least in part independent of HIF 101,102,103,104.
