Tumor Necrosis Factor Receptor-Associated Factors (TRAFs) are a family of adapter proteins that bind an unusual ubiquitin-conjugating enzyme, Ubc13, which produces polyubiquitin chains linked at lysine 63 of ubiquitin. These lysine 63-linked ubiquitin polymers trigger changes in protein activity. Ubiquitination by Ubc13 of TRAFs and the various protein kinases to which TRAFs bind is recognized as more ..

Tumor Necrosis Factor Receptor-Associated Factors (TRAFs) are a family of adapter proteins that bind an unusual ubiquitin-conjugating enzyme, Ubc13, which produces polyubiquitin chains linked at lysine 63 of ubiquitin. These lysine 63-linked ubiquitin polymers trigger changes in protein activity. Ubiquitination by Ubc13 of TRAFs and the various protein kinases to which TRAFs bind is recognized as a critical step in signaling by TNFRs, TLRs, NLRs, and T-cell and B-cell antigen receptors (TCR/BCR) during innate and acquired immune responses. Since aberrant signaling by these receptor systems is linked to a wide variety of autoimmune, inflammatory, and infectious diseases; compounds that neutralize Ubc13 may prove useful as a novel type of immunosuppressive or anti-inflammatory agent.
The goal of this screen is to measure the biochemical activity of Ubc13 in vitro, based on the principal of time-resolved fluorescence resonance energy transfer (TR-FRET). Ubiquitination reactions contain purified recombinant proteins (E1, Ubc13 and Uev1a) mixed with labeled ubiquitins (terbium- and fluorescein-labeled) and ATP-regenerating system to trigger polyubiquitin chain synthesis in vitro. The reaction product is mixed chains of terbium-(fluorescence donor) and fluorescein-(fluorescene acceptor) conjugated Ubiquitin, thus creating the basis for robust TR-FRET signals.
This dose response assay is developed and performed to confirm hits originally identified in "uHTS identification of UBC13 Polyubiquitin Inhibitors via a TR-FRET Assay" (AID 485273) and to study the structure-activity relationship on analogs of the confirmed hits. Compounds are either acquired from commercial sources or synthesized internally.

Comment
Compounds that demonstrated an IC50_Mean <20 uM in both assays are defined as inhibitors of the reaction.
1) First tier (0-40 range) is reserved for primary screening data and is not applicable in this assay.
2) Second tier (41-80 range) is reserved for dose-response confirmation data and is not applicable in this assay
3) Third tier (81-100 range) is reserved for resynthesized true positives and their analogues
a. Inactive compounds of the confirmatory stage are assigned a score value equal 81.
b. The score is linearly correlated with a compound potency and, in addition, provides a measure of the likelihood that the compound is not an artifact based on the available information.
c. The Hill coefficient is taken as a measure of compound behavior in the assay via an additional scaling factor QC:
QC = 2.6*[exp(-0.5*nH^2) - exp(-1.5*nH^2)]
This empirical factor prorates the likelihood of target-specific compound effect vs. its non-specific behavior in the assay. This factor is based on expectation that a compound with a single mode of action that achieved equilibrium in this assay demonstrates the Hill coefficient value of 1. Compounds deviating from that behavior are penalized proportionally to the degree of their deviation.
d. Summary equation that takes into account the items discussed above is
Score = 82 + 3*(pIC50 - 3)*QC,
where pIC50 is a negative log(10) of the IC50 value expressed in mole/L concentration units. This equation results in the Score values above 85 for compounds that demonstrate high potency and predictable behavior. Compounds that are inactive in the assay or whose concentration-dependent behavior are likely to be an artifact of that assay will generally have lower Score values.
