Description générale
A cell-permeable, reversible, potent and selective inhibitor of Casein Kinase (CK1) that inhibits the CK1δ (IC50 = 0.7-1.3 µM) and CK1ε (IC50 = 0.6-1.4 µM) isozymes. Also inhibits CK1α1 at much higher concentrations (IC50 = 11-21 µM). The inhibition is competitive with respect to ATP. Has only a trivial effect on p34cdc2 and p55fyn (IC50s >100 µM). Blocks the phosphorylation of p53 by CK1δ and CK1ε, thereby modulating p53′s effect on the cell cycle. At low micromolar concentrations, IC261 inhibits cytokinesis causing a transient mitotic arrest.

Also inhibits CK1α1 at much higher concentrations (IC50 = 11-21 µM). The inhibition is competitive with respect to ATP. Only weakly inhibits PKA, p34cdc2, and p55fyn (IC50s >100 µM). At low micromolar concentrations, IC261 inhibits cytokinesis causing a transient mitotic arrest.

The p53 tumour suppressor protein plays a key role in the integration of stress signals. Multi-site phosphorylation of p53 may play an integral part in the transmission of these signals and is catalysed by many different protein kinases including an

The p53-targeted kinases casein kinase 1delta (CK1delta) and casein kinase 1epsilon (CK1epsilon) have been proposed to be involved in regulating DNA repair and chromosomal segregation. Recently, we showed that CK1delta localizes to the spindle apparatus and the centrosomes in cells

Members of the casein kinase-1 family of protein kinases play an essential role in cell regulation and disease pathogenesis. Unlike most protein kinases, they appear to function as constitutively active enzymes. As a result, selective pharmacological inhibitors can play an
