Function

[STK24_HUMAN] Serine/threonine-protein kinase that acts on both serine and threonine residues and promotes apoptosis in response to stress stimuli and caspase activation. Mediates oxidative-stress-induced cell death by modulating phosphorylation of JNK1-JNK2 (MAPK8 and MAPK9), p38 (MAPK11, MAPK12, MAPK13 and MAPK14) during oxidative stress. Plays a role in a staurosporine-induced caspase-independent apoptotic pathway by regulating the nuclear translocation of AIFM1 and ENDOG and the DNase activity associated with ENDOG. Phosphorylates STK38L on 'Thr-442' and stimulates its kinase activity. Regulates cellular migration with alteration of PTPN12 activity and PXN phosphorylation: phosphorylates PTPN12 and inhibits its activity and may regulate PXN phosphorylation through PTPN12. May act as a key regulator of axon regeneration in the optic nerve and radial nerve.^[1] ^[2] ^[3] ^[4] ^[5]

Publication Abstract from PubMed

Increasing evidence suggests key roles for members of the mammalian Sterile20-like (MST) family of kinases in many aspects of biology. MST3 is a member of the STRIPAK complex, the deregulation of which has recently been associated with cancer cell migration and metastasis. Targeting MST3 with small-molecule inhibitors may be beneficial for the treatment of certain cancers, but little information exists on the potential of kinase inhibitor scaffolds to engage with MST3. In this study we screened MST3 against a library of 277 kinase inhibitors using differential scanning fluorimetry and confirmed 14 previously unknown MST3 inhibitors by X-ray crystallography. These compounds, of which eight are in clinical trials or FDA approved, comprise nine distinct chemical scaffolds that inhibit MST3 enzymatic activity with IC50 values between 0.003 and 23 mum. The structure-activity relationships explain the differential inhibitory activity of these compounds against MST3 and the structural basis for high binding potential, the information of which may serve as a framework for the rational design of MST3-selective inhibitors as potential therapeutics and to interrogate the function of this enzyme in diseased cells.
