Recombinant Human His6-UbcH6/UBE2E1 Protein, CF Summary

Product Specifications

>95%, by SDS-PAGE under reducing conditions and visualized by Colloidal Coomassie® Blue stain
Recombinant Human His6-UbcH6/UBE2E1 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-UbcH6/UBE2E1 concentration of 0.1-1 μM.
E. coli-derived human UbcH6/UBE2E1 protein
Contains an N-terminal Gly-Ser-Ser and 6-His tag
Accession #
Predicted Molecular Mass
23 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: UbcH6/UBE2E1

Ubiquitin-conjugating Enzyme H6 (UbcH6), also known as Ubiquitin-conjugating Enzyme E2E 1 (UBE2E1), is a ubiquitously expressed protein with a predicted molecular weight of 21 kDa. Human UbcH6/UBE2E1 shares 99% and 100% amino acid sequence identity with mouse and rat UBE2E1, respectively. UbcH6/UBE2E1 mediates the selective degradation of short-lived and abnormal proteins (1). UbcH6/UBE2E1 catalytic activity is modulated following the addition of the Ubiquitin-like protein ISG15 to Lys136 (2). In the nucleus, the N-terminal fragment of UbcH6/UBE2E1 interacts with the Ubiquitin ligase (E3) TRIM21 to mediate substrate ubiquitination (3,4). UbcH6/UBE2E1 also interacts with the viral E3, ICP0, during HSV-1 infection (5). In addition, UbcH6/UBE2E1-dependent protein ubiquitination is implicated in polyglutamine tract disorders such as ataxia (6,7).
