Recombinant Human/Mouse/Rat UBE2M/Ubc12 Protein, CF Summary

Product Specifications

>95%, by SDS-PAGE under reducing conditions and visualized by Colloidal Coomassie® Blue stain.
Recombinant Human UBE2M/Ubc12 is a member of the NEDD8-conjugating (E2) enzyme family that receives NEDD8 from a NEDD8-activating (E1) enzyme and subsequently interacts with a NEDD8 ligase (E3) to conjugate NEDD8 to substrate proteins. Reaction conditions will need to be optimized for each specific application. We recommend an initial Recombinant Human UBE2M/Ubc12 concentration of 0.1-1 μM.
E. coli-derived UBE2M/Ubc12 protein
Met1 - Lys183

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.


Formulation Supplied as a 0.2 μm filtered solution in HEPES, NaCl, TCEP and Glycerol.

Background: UBE2M/Ubc12

Ubiquitin-conjugating Enzyme E2M (UBE2M), also known as Ubiquitin-conjugating Enzyme 12 (Ubc12), is a ubiquitously expressed protein with a predicted molecular weight of 20 kDa. UBE2M/Ubc12 is highly conserved, and the human ortholog shares 100% amino acid identity with mouse and rat UBE2M. UBE2M/Ubc12 mediates conjugation of the Ubiquitin-like protein Neural Precursor Cell Expressed, Developmentally Down-regulated 8 (NEDD8) to substrate proteins (1). Neddylation requires the coordinated activities of UBE2M/Ubc12 and the APPBPI/UBA3 heterodimer, a NEDD8-activating (E1) enzyme (2,3). The NEDD8 pathway is essential for the viability of many organisms and plays important roles in morphogenesis and cell cycle progression (4-5). UBE2M/Ubc12-dependent neddylation modulates the levels of p27/Kip1, beta-Catenin, Cdc53/Cul1, and other members of the Cullin family (6-9).
