Inhibitor Comments
DMAT inhibits CK2 kinase activity in vitro (purified and endogenous enzyme assays), and promotes Jurkat cell apoptosis [5].
Immunopharmacology Comments
Protein kinase CK2 inhibition prevents TH17 cell development, driving the TH17/Treg balance towards Treg generation, an action which may find clinical utility in treating TH17-driven autoimmune diseases [8].
General Comments
Casein kinase 2 (CK2) is a heterotetrameric protein kinase, made up of 2 β subunits with two other subunits of α and/or α' composition. CK2 is the kinase that activates the transcriptional regulator BRD4.
