Application

PR-619 has been used:
  • as a component of lysis buffer and also as a deubiquitinase inhibitor to treat proteins derived from SILAC-labeled Jurkat cells
  • as a pan-deubiquitinase inhibitor to study its effect on adenoassociated virus (AAV) transduction
  • in radioimmunoprecipitation assay buffer (RIPA) buffer used for ubiquitination assays

Biochem/physiol Actions

PR-619 is a cell permeable broad spectrum deubiquitylating enzymes (DBUs) inhibitor. PR-619 induces the accumulation of polyubiquitylated proteins in cells without directly affecting proteasome activity.

2,6-Diaminopyridine-3,5-bis(thiocyanate) (PR-619) is a broad-spectrum deubiquitinating enzyme (DUB) inhibitor that has been employed in cell-based studies as a tool to investigate the role of ubiquitination in various cellular processes. Here, we demonstrate that in addition to its action as a
