Notes: Casein kinase 2 (CK2) is a constitutive protein kinase involved in many signal transduction pathways. CK2 is known to negatively regulate apoptosis, and its activity is increased in many proliferating tissues and tumors. 4,5,6,7-Tetrabromobenzimidazole is a selective, ATP-competitive inhibitor of CK2 with Ki values ranging from 0.5-1 µM in rat liver, S. cerevisiae, C. tropicalis, and N. crassa.{30429} It is inactive against PKA and PKC and a relatively weak inhibitor of CK1 (Ki = 54.4-64.2 µM).{30429}
