Casein Kinase (CK) <strong>Inhibitor</strong>s<br />
Casein kinases I and II (CKI and CKII) are highly<br />
conserved, ubiquitous serine/threonine protein kinases<br />
that play a significant role in neoplasia and cell survival.<br />
CKI can be found in the nucleus and the cytosol and<br />
is bound to the cytoskeleton and membranes. The CKI<br />
family consists of several isoforms (CKIa, b, g1, g2,<br />
g3, d, and e) encoded by seven distinct genes. It plays a<br />
significant role in the regulation of circadian rhythm,<br />
intracellular trafficking and also acts as a regulator of<br />
Wnt signaling, nuclear import, and the progression of<br />

Phosphorylation/Dephosphorylation<br />
Alzheimer’s disease. CKII has traditionally been classified<br />
as a messenger-independent protein serine/threonine<br />
kinase and consists of two catalytic and two regulatory<br />
subunits. It plays an important role in the progression<br />
of the cell cycle and in maintenance of cell viability.<br />
It is highly conserved and is known to phosphorylate<br />
about 300 different proteins. CKII activity is required at<br />
transition points of the cell cycle. Excessive activity of<br />
CKII has been linked to oncogenic transformation and the<br />
development of primary and metastatic tumors.<br />

2-yl)benzamide}<br />
A cell-permeable, potent, and relatively specific ATP-competitive inhibitor of CKI<br />
(IC 50 = 200 nM from S. pombe; 300 nM for CKId). Shown to be ~ 0-fold more potent<br />
than IC26 (Cat. No. 400090; IC 50 = 2.5 mM for CKI).<br />

Tetrabromobenzotriazole)<br />
A cell-permeable, highly selective, ATP/GTP-competitive CKII inhibitor<br />
(IC 50 = 900 nM and .6 mM for rat liver and human recombinant CKII, respectively<br />
and DYRK (IC 50 < mM for DYRK a).<br />

218699 (CKII <strong>Inhibitor</strong> II, DMAT; 2-Dimethylamino-4,5,6,7-tetrabromo-1H-benzimidazole)<br />
A cell-permeable, potent, high affinity and ATP-competitive inhibitor of CKII (IC 50 = 40 nM<br />
rat liver; K i = 40 nM). Displays ~ 300 fold greater selectivity over CKI (IC 50 > 200 mM) and is<br />
superior to CKII inhibitor, TBB (Cat. No. 2 8697).<br />
