UBE2V2 protein lacks independent ubiquitin ligase activity and forms a functional heterodimer with UBE2N. Together, they catalyze nonclassical polyubiquitin chain synthesis ("Lys-63"), distinct from proteasome-driven degradation. UBE2V2 Protein, Human (sf9, His, strep) is the recombinant human-derived UBE2V2 protein, expressed by Sf9 insect cells, with N-His and N-Strep labeled tag.
