Protein
E3 ubiquitin-protein ligase DCST1
Gene
DCST1
Organism
Homo sapiens (Human)
Status
Functioni
E3 ubiquitin-protein ligase which mediates 'Lys-48'-linked ubiquitination of STAT2 and induces its proteosomal degradation thereby negatively regulating type-I-interferon signaling.1 Publication
Catalytic activityi
S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine + [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-cysteine + N6-ubiquitinyl-[acceptor protein]-L-lysine.1 Publication
: protein ubiquitination Pathwayi
This protein is involved in the pathway protein ubiquitination, which is part of Protein modification.1 PublicationView all proteins of this organism that are known to be involved in the pathway protein ubiquitination and in Protein modification.
