Protein kinase B (PKB/Akt) is a pivotal regulator of diverse metabolic, phenotypic, and antiapoptotic cellular controls and has been shown to be a key player in cancer progression. Here, using fluorescent reporters, we shown in cells that, contrary to in vitro analyses, 3-phosphoinositide-dependent protein kinase 1 (PDK1) is complexed to its substrate, PKB.(More)
Lipids are actively involved in many cellular processes. Their roles pivot toward determining membrane structure, compartment targeting, and membrane fusion but also regulation of cell signaling via their interactions with proteins and the production of second messengers. As they play a key role in cell signaling, the study of protein-protein interaction(More)
In Myxococcus xanthus the gliding motility machinery is assembled at the leading cell pole to form focal adhesions, translocated rearward to propel the cell, and disassembled at the lagging pole. We show that MglA, a Ras-like small G-protein, is an integral part of this machinery. In this function, MglA stimulates the assembly of the motility complex by(More)
The PKB (protein kinase B) and PKC (protein kinase C) families display highly related catalytic domains that require a largely conserved series of phosphorylations for the expression of their optimum activities. However, in cells, the dynamics of these modifications are quite distinct. Based on experimental evidence, it is argued that the underlying(More)
