Ubiquitination Evaluation Platform (UbEP™)

Regulated protein degradation is an essential aspect of cell signaling. Recent evidence that pharmacological inhibition of the proteasome can be efficacious in the treatment of human cancers (Bortezimib, treatment of multiple myeloma) has set the stage for attempts to selectively inhibit the activities of disease-specific components of ubiquitin proteasome system.

At we have developed in-house the technology and methods of the Ubiquitination Evaluation Platform (UbEPTM™) to further examine the hits scored and prioritized through vHTS system. We also evaluate those from custom generated or identified drug leads. The platform includes the following assays:

  1. E1 thioester assay
  2. E2 thioester assay
  3. E3 auto-ubiquitination assay
  4. E3-mediated substrate ubiquitination assay
