Recombinant Human His6-UBE2G1 Protein, CF Summary

Product Specifications

>95%, by SDS-PAGE under reducing conditions and visualized by Colloidal Coomassie® Blue stain.
Recombinant Human His6-UBE2G1 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 Recombinant Human His6-UBE2G1 concentration of 0.1-1 μM.
E. coli-derived human UBE2G1 protein
Contains an N-terminal 6-His tag

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: UBE2G1

Ubiquitin-conjugating Enzyme E2G 1 (UBE2G1) is a 170 amino acid (aa) member of the Ubiquitin-conjugating (E2) enzyme family with a predicted molecular weight of 19.5 kDa. The human protein shares 100% aa sequence identity with the mouse and rat orthologs.  UBE2G1 has an E2 catalytic core domain with an active site cysteine residue that is required for the formation of a thioester bond with Ubiquitin (1). The expression level of UBE2G1 is downregulated when miR-199a is overexpressed, suggesting that UBE2G1 mRNA is targeted by miR-199a (2). UBE2G1 has been reported to function with the CRL4(Cdt2) Ubiquitin ligase (E3) to promote the poly-ubiquitination and degradation of Cdt1 (3). Reduced expression of UBE2G1 in medulloblastoma tumors has also been reported, suggesting that it may act as a tumor suppressor (4). This protein contains an N-terminal 6-His tag.
