Webprotein SUMO-1. In particular, we demonstrate that p14ARF interacts with the SUMO E2 conjugating enzyme, Ubc9 and enhances the sumoylation of its binding partners, hdm2, E2F-1, HIF-1α, TBP-1 and p120E4F. Furthermore, p14ARF-induced sumoylation is abrogated by a subset of melanoma-associated p14 ARF mutations. These results … Web31 de jul. de 2014 · The ubiquitin-like SUMO (small ubiquitin-related modifier) system is a post-translational protein modification pathway in eukaryotes [ [ 1 ], [ 2 ]]. SUMOylation is a highly dynamic process, where deconjugation (deSUMOylation) is catalyzed by a family of cysteine proteases, termed SUMO-specific proteases or SUMO isopeptidases.
