Recombinant Human His6-UBE2N/UBE2V2 Complex Protein, CF Summary

Product Specifications

>95%, by SDS-PAGE under reducing conditions and visualized by Colloidal Coomassie® Blue stain

Recombinant Human His6-­UBE2N/UBE2V2 Complex is a member of the Ubiquitin­ conjugating (E2) enzyme family that receives Ubiquitin from a Ubiquitin­ activating (E1) enzyme and subsequently interacts with a Ubiquitin ligase (E3) to conjugate Ubiquitin to substrate proteins.  Reaction conditions will need to be optimized for each specific application.  We recommend an initial His-UBE2N/UBE2V2 Complex concentration of 0.1­-1 μM.

E. coli-derived human UBE2N/UBE2V2 Complex protein
Contains an N-terminal 6-His tag
Accession # P61088 (UBE2N)/Q15819 (UBE2V2)
Predicted Molecular Mass

18 kDa (UBE2N), 17 kDa (UBE2V2)

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: UBE2N/UBE2V2 Complex

Ubiquitin ­conjugating Enzyme E2N (UBE2N), also known as Ubiquitin­ conjugating Enzyme 13 (Ubc13), forms a functional complex with the catalytically inactive UBE2V2 (human homologue of yeast MMS2) protein (1). Human UBE2N/Ubc13 shares 100% and 99% amino acid (aa) sequence identity with the mouse and rat orthologs, respectively, while human UBE2V2 shares 99% aa sequence identity with its mouse and rat orthologs. The UBE2N/UBE2V2 Complex functions with Ubiquitin ligases (E3s), including RNF111 and RNF8, to synthesize Lys63-­linked Ubiquitin chains (2,3) that can either be unanchored or attached to target proteins (4, 5). The UBE2N/UBE2V2 complex has important roles in facilitating responses to various forms of DNA damage (2, 6).
