UB2D3 Protein, Human (Sf9, His, Strep)

The UBE2D3 protein is a key player in ubiquitination. It accepts ubiquitin from the E1 complex and covalently attaches it to a variety of proteins, demonstrating multifunctionality. It catalyzes "Lys-11" and "Lys-48" linked polyubiquitination in vitro, regulating protein ubiquitination patterns. UB2D3 Protein, Human (Sf9, His, Strep) is the recombinant human-derived UB2D3 protein, expressed by Sf9 insect cells , with N-Strep, N-8*His labeled tag. The total length of UB2D3 Protein, Human (Sf9, His, Strep) is 146 a.a., .

UBE2D3, a pivotal participant in the ubiquitination process, accepts ubiquitin from the E1 complex and orchestrates its covalent attachment to diverse proteins, showcasing its versatility . In vitro, UBE2D3 catalyzes both 'Lys-11'- and 'Lys-48'-linked polyubiquitination, underscoring its role in regulating protein ubiquitination patterns. Collaborating with the E2 CDC34 and the SCF(FBXW11) E3 ligase complex, UBE2D3 contributes to the polyubiquitination of NFKBIA, leading to subsequent proteasomal degradation. Functioning as an initiator E2, UBE2D3 primes the phosphorylated NFKBIA target at positions 'Lys-21' and/or 'Lys-22' with a monoubiquitin, a crucial step preceding ubiquitin chain elongation by CDC34. Notably, UBE2D3 serves as an initiator E2, in conjunction with RNF8, for the priming of PCNA, pivotal in the DNA damage tolerance pathway activated after DNA damage caused by UV or chemical agents during S-phase. Furthermore, UBE2D3 engages with various E3 ligases, including BRCA1/BARD1, MDM2, TOPORS, CBL, STUB1, RNF135, and ZNF598, showcasing its involvement in diverse ubiquitination processes, ranging from DNA repair to the regulation of viral RNA-dependent signaling pathways.
