Biochemical Activity (Desumoylation)
An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation.

SENP1 mediates TNF-induced desumoylation and cytoplasmic translocation of HIPK1 to enhance ASK1-dependent apoptosis.
We have previously shown that tumor necrosis factor (TNF)-induced desumoylation and subsequent cytoplasmic translocation of HIPK1 are critical for ASK1-JNK activation. However, the mechanism by which TNF induces desumoylation of HIPK1 is unclear. Here, we show that SENP1, a SUMO-specific protease, specifically deconjugates SUMO from HIPK1 in vitro and in vivo. In resting endothelial cells (ECs), SENP1 is localized in ... [more]
