Individuals carrying a mutation in one of the three cerebral cavernous malformation genes (CCM1/KRIT1, CCM2, CCM3) cannot be clinically distinguished, raising the possibility that they act within common molecular pathways. In this study, we demonstrate that CCM3 (PDCD10) coprecipitates and colocalizes with CCM2. We also show that CCM3 directly binds to serine/threonine kinase 25 (STK25, YSK1, SOK1) and the phosphatase domain of Fas-associated phosphatase-1 (FAP-1, PTPN13, PTP-Bas, PTP-BL). CCM3 is phosphorylated by STK25 but not by its other Yeast-Two hybrid interactor STK24, whereas the C-terminal catalytic domain of FAP-1 dephosphorylates CCM3. Finally, our experiments reveal that STK25 forms a protein complex with CCM2. Thus, our data link two proteins of unknown function, CCM3 and STK25, with CCM2, which is part of signaling pathways essential for vascular development and CCM pathogenesis.

The mammalian MST kinase family, which is related to the Hippo kinase in Drosophila melanogaster, includes five related proteins: MST1 (also called STK4), MST2 (also called STK3), MST3 (also called STK24), MST4, and YSK1 (also called STK25 or SOK1). MST kinases are emerging as key signaling molecules that influence cell proliferation, organ size, cell migration, and cell polarity. Here we review the regulation and function of these kinases in normal physiology and pathologies, including cancer, endothelial malformations, and autoimmune disease.

The mammalian sterile 20-like (MST) family, which belongs to the serine/threonine protein kinase superfamily, has five members that can be found in mammals: STK3 (also called MST2), STK4 (MST1), STK24 (MST3), STK25 (YSK1 or SOK1), and STK26 (MST4). The MST kinases have key roles in apoptosis, immune regulation, inflammatory responses, cancer, and cell proliferation in mammals, whereas the roles and transcriptional regulatory mechanism of these kinases in teleost fish are still unclear. In this study, four STK genes (CiSTK3, CiSTK24, CiSTK25, and CiSTK26) were cloned and analyzed in grass carp (Ctenopharyngodon idella). All four STK genes were broadly expressed in the examined tissues, while their relative expression levels differed. In addition, after exposure to the grass carp reovirus, mRNA expression levels of the four STK genes were altered to different levels in the immune organs, and the levels were dramatically altered in the blood. Subcellular localization indicated that all four STK proteins were localized in the cytoplasm of transfected cells. Moreover, bimolecular fluorescence complementation analysis revealed that mouse protein-25 could interact with CiSTK3, CiSTK24, CiSTK25, and CiSTK26 independently in grass carp. Thus, our findings provide new insights for understanding the functions of the MST family in teleosts.

Since the discovery of the mammalian sterile twenty (MST) kinase family of proteins (MST1/STK4, MST2/STK3, MST3/STK24, and SOK1/STK25), much has been done that adds to our knowledge of their structure, regulation, and function. In the last few years, a series of articles has unveiled a previous unknown relation of these kinases with metabolic regulation and the homeostasis of metabolic tissues. The aim of this review is to bring together this body of data to provide a detailed picture of the current knowledge about these proteins, metabolism, and some of the associated diseases.

One of the CCM genes, CCM3/PDCD10, binds to the protein kinase family GCKIII, which comprises MST3/STK24, SOK1/STK25, and MST4/STK26. These proteins have been shown to have the same effect as CCM3, both in endothelial cells and in animal models such as zebrafish and are most likely involved in CCM pathogenesis. We describe here an in vitro kinase assay of GCKIII proteins which can be used to study their regulation in endothelial and other cells under different circumstances.
