Recombinant Human His6-Ufc1 Protein, CF Summary

Product Specifications

>95%, by SDS-PAGE under reducing conditions and visualized by Colloidal Coomassie® Blue stain
Recombinant Human His6-Ufc1 is a member of the UFM1-conjugating (E2) enzyme family that receives UFM1 from a UFM1-activating (E1) enzyme and subsequently interacts with a UFM1 ligase (E3) to conjugate UFM1 to substrate proteins. Reaction conditions will need to be optimized for each specific application. We recommend an initial Recombinant Human His6-Ufc1 concentration of 0.1-1 μM.
E. coli-derived human Ufc1 protein
Contains an N-terminal 6-His tag
Accession #
Predicted Molecular Mass
22 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.


Formulation X mg/ml (X μM) in 50 mM HEPES pH 8.0, 100 mM NaCl, 10% glycerol

Background: Ufc1

Ubiquitin-fold Modifier Conjugating Enzyme 1 (Ufc1) has been identified as an E2-like conjugating enzyme for Ubiquitin Fold Modifier 1 (Ufm1) (1). Ufc1 is a 116 amino acid (aa) protein with a predicted molecular weight of 19 kDa. Human Ufc1 exhibits 97% and 98% aa identity to its mouse and rat orthologs, respectively. The process of attaching Ufm1 to target proteins is termed ufmylation. It is thought to occur in a manner analogous to the ubiquitin system, including stepwise enzymatic reactions involving Ubiquitin-activating (E1)-, Ubiquiting-conjugating (E2)-, and Ubiquitin Ligase (E3)-like enzymes. In addition to Ufc1, other members of the Ufm1-conjugation system include the E1-like enzyme Uba5, E3-like enzyme Ufl1, and deconjugating enzymes UfSP1 and UfSP2 (1-3). This protein contains an N-terminal His6 tag.
