Application

TBB was used to study casein kinase 2-dependent phosphorylation of DNA damage mediator protein MDC1.

Biochem/physiol Actions

TBB binds to the Val66 residue of casein kinase-2 and inhibits the binding of ATP/GTP. TBB is cell permeable; it induces caspase-dependent apoptosis and degrades hematopoietic lineage cell-specific protein 1 in Jurkat cells.
TBB is a highly selective, ATP/GTP-competitive inhibitor of casein kinase-2 (CK2) (IC50 = 900 nM and 1.6 mM, using rat liver and recombinant human CK2, respectively).

The specificity of 4,5,6,7-tetrabromo-2-azabenzimidazole (TBB), an ATP/GTP competitive inhibitor of protein kinase casein kinase-2 (CK2), has been examined against a panel of 33 protein kinases, either Ser/Thr- or Tyr-specific. In the presence of 10 microM TBB (and 100 microM ATP)

Mammalian cells respond to DNA double-strand breaks (DSBs) by recruiting DNA repair and cell-cycle checkpoint proteins to such sites. Central to these DNA damage response (DDR) events is the DNA damage mediator protein MDC1. MDC1 interacts with several DDR proteins

Incubation of Jurkat cells with 4,5,6,7-tetrabromobenzotriazole (TBB), a specific inhibitor of protein kinase CK2, induces dose-and time-dependent apoptosis as judged by several criteria. TBB-promoted apoptosis is preceded by inhibition of Ser/Thr phosphorylation of haematopoietic lineage cell-specific protein 1 (HS1) and
