Genetic alterations in numerous signaling pathways contribute to human pathologies such as cancer and diabetes. Combinatorial drug therapies designed to target multiple signaling pathways hold promise in treating human disease, but this critically depends upon an understanding of the interactions of signaling molecules.<\/p>\n\n\n\n<p>Many oncogenes activate signaling pathways originating from receptor tyrosine kinases at the cell surface. One major pathway turned on during neoplasia is the phosphoinositide 3-kinase (PI3K) pathway. PI3K is a lipid kinase that regulates the subcellular distribution of other signaling proteins, and in particular members of the AGC kinase family. With over 60 family members, the AGC kinase family regulates a host of cellular functions including proliferation, survival, shape and mobility \u2013 typically the arsenal of tools a cell needs to successfully become a malignant tumor. Several tumor suppressors that are often disabled in human cancer normally operate to suppress PI3K signaling to various AGC kinases.<\/p>\n\n\n\n<p>One member of the AGC kinase family of particular interest is PDK1. PDK1 is a master switch regulating the activity of other kinases that are often dysregulated during neoplasia. We are interested in the mechanism of PDK1 regulation, including how it phosphorylates its various substrates, its subcellular shuttling, and its interaction with PI3K.<\/p>\n\n\n\n<p>Methodologies used in the lab include molecular biology, cell biology, microscopy, tissue culture, gene expression, protein purification and biochemistry.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Sub-Disciplines<\/h2>\n\n\n\n<p>Cancer Biology, Cell Biology and Molecular Biology<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Representative publications:<\/h2>\n\n\n\n<p>Couzens AL, Gill RM, Scheid MP.
