Recombinant Human His6UBE2S Protein, CF Summary

Product Specifications

>95%, by SDS-PAGE under reducing conditions and visualized by Colloidal Coomassie® Blue stain
Recombinant Human His6-UBE2S 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-UBE2S concentration of 0.1-1 μM.
E. coli-derived human UBE2S protein
Contains an N-terminal 6-His tag
Accession #
Predicted Molecular Mass
36 kDa

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: UBE2S

Ubiquitin-conjugating Enzyme E2S (UBE2S), also known as E2-EPF, is a widely expressed protein with a predicted molecular weight of 26 kDa (1). Human UBE2S shares 92% and 93% amino acid sequence identity with mouse and rat UBE2S, respectively. UBE2S expression oscillates in a cell cycle-dependent fashion, and it influences cell cycle progression by mediating the Ubiquitin-dependent proteolysis of mitotic regulators (2-4). UBE2S interacts with APC/C, a Ubiquitin ligase (E3), to catalyze the elongation of Lys11-linked Ubiquitin chains on APC/C substrates that have been mono-ubiquitinated by UbcH10/UBE2C or UbcH5/UBE2D (3-7). UBE2S is overexpressed in multiple human cancers and targets the tumor suppressor pVHL for proteasomal degradation, which stabilizes HIF-1 alpha and promotes tumor progression (8).
