描述 | Homeodomain-interacting protein kinase 2 (HIPK2) is a serine/threonine protein kinase involved in cell proliferation and survival. tBID is a potent and selective inhibitor of HIPK2 with an IC50 value of 0.33 μM. It inhibits HIPK2 through ATP competition with a Ki value of 200 nM. When tBID was tested at the concentration of 1 μM, the residual activities of HIPK1 and HIPK3 were 39% and 53%, respectively, as compared to HIPK2 (31% residual activity). tBID also displayed inhibitory potential against CK2 with an IC50 value of 5.50 μM. The treatment of HepG2 cells with 10 and 50 μM of TBID led to a reduction of endogenous HIPK2 activity in a dose-dependent manner. TBID treatment (10 and 50 μM) also greatly reduced the level of p53 Ser46 without affecting the amount of p53[1]. Mechanism: tBID is an ATP-competitive inhibitor of HIPK2. It inhibits HIPK2 by interacting with its hinge region through hydrophobic interactions between Val 213, Val 261, Phe 277, Leu 280, Met 331, Ile 345, and the tetrabromine moiety[1]. |
