Biological Information

Background Information:

Homeodomain-interacting protein kinase 2 (HIPK2), a serine/threonine kinase, has been described as a member of a family of nuclear kinases that act as co-repressors for homeodomain transcription factors. HIPK2 can activate p53-mediated transcriptional regulation of MDM2 and antagonize Myc/Ras-induced transformation. HIPK2 may play an important role in the regulation of p53 apoptotic function. Inhibition of HIPK2 may inhibit apoptosis and facilitate tumorigenesis.

Testing Information

Procedure Summary:

Human recombinant protein kinase HIPK2 expressed in insect Sf21 cells is used. Test compound and/or vehicle is preincubated with 341 mU/ml enzyme‡ in modified MOPS buffer pH 7.2 for 15 minutes at 37°C. The reaction is initiated by addition of 50 µg/ml myelin basic protein (MBP), 10 µM ATP and 0.25 µCi [γ32P]ATP for another 30 minute incubation period and terminated by further addition of 3% H3PO4. An aliquot is removed and counted to determine the amount of [32P]MBP formed. Compounds are screened at 10 µM.
