DSK2B

Gene
DSK2B
Protein
Ubiquitin domain-containing protein DSK2b
Organism
Arabidopsis thaliana
Length
551 amino acids
Function
Binds and presumably selects ubiquitin-conjugates for destruction. Prefers multiubiquitin chains rather than single ubiquitins, with a binding affinity for 'Lys-48'-linked ubiquitin chains. Acts as a ubiquitin receptor that associates with the 26S proteasomal docking subunit RPN10 for the indirect recognition of ubiquitinated substrates of ubiquitin/26S proteasome-mediated proteolysis (UPP).
