A regulatory link between p70s6k and pkb was demonstrated, as pdk1 was found to selectively phosphorylate p70s6k at thr229. More importantly, pdk1 activated p70s6k in vitro and in vivo, whereas the catalytically inactive pdk1 blocked insulin-induced activation of p70s6k. One of the most studied events controlled by ptdins(3,4,5)p3, comprises the activation of a of agc family protein kinases, including isoforms of protein kinase b (pkb)/akt, p70 ribosomal s6 kinase (s6k), serum- and glucocorticoid-induced protein kinase (sgk) and protein kinase c (pkc), which play crucial roles in regulating physiological processes relevant to metabolism, growth, proliferation and survival. Here, we review recent biochemical, genetic and structural studies on the 3-phosphoinositide-dependent protein kinase-1 (pdk1), which phosphorylates and activates the agc kinase members regulated by pi 3-kinase. We also discuss whether inhibitors of pdk1 might have chemotherapeutic potential in the treatment of cancers in which the pdk1-regulated agc kinases are constitutively activated.

Neurofascin, L1, NrCAM, NgCAM, and neuroglian are membrane-spanning cell adhesion molecules with conserved cytoplasmic domains that are believed to play important roles in development of the nervous system. This report presents biochemical evidence that the cytoplasmic domains of these molecules associate directly with ankyrins, a family of spectrin-binding proteins located on the cytoplasmic surface of specialized plasma membrane domains.

Kindlin binds migfilin tandem LIM domains and regulates migfilin focal adhesion localization and recruitment dynamics. Two integrin-binding proteins present in FAs, kindlin-1 and kindlin-2, are important for integrin activation, FA formation, and signaling. By binding filamin, migfilin provides a link between kindlin and the actin cytoskeleton.

Here, we have shown that Plk1 is responsible for part of the phosphorylation of Myt1 during M phase. The kinase activity of human Myt1 is reported to be decreased during M phase, and the decreased activity correlates with hyperphosphorylated forms of Myt1 (35, 37). We then tested the ability of these mutant forms of Myt1 (GST fusion proteins), to serve as a substrate for Plk1 in vitro. Quantification of the result (Fig. 5C) showed that Ser-426 is the major phosphorylation site by Plk1 in vitro and Thr-495 the second major site.

Sprouty-related, EVH1 domain-containing (SPRED) proteins negatively regulate RAS/mitogen-activated protein kinase (MAPK) signaling following growth factor stimulation. This inhibition of RAS is thought to occur primarily through SPRED1 binding and recruitment of neurofibromin, a RasGAP, to the plasma membrane. Here, we report the structure of neurofibromin (GTPase-activating protein [GAP]-related domain) complexed with SPRED1 (EVH1 domain) and KRAS. The structure provides insight into how the membrane targeting of neurofibromin by SPRED1 allows simultaneous interaction with activated KRAS.

Here we show that different regions of the intracellular domain of DCC directly interacted with the tyrosine kinases Src and focal adhesion kinase (FAK). Netrin activated both FAK and Src and stimulated tyrosine phosphorylation of DCC. Inhibition of Src family kinases reduced DCC tyrosine phosphorylation and blocked both axon attraction and outgrowth of neurons in response to netrin. Mutation of the tyrosine phosphorylation residue in DCC abolished its function of mediating netrin-induced axon attraction. On the basis of our observations, we suggest a model in which DCC functions as a kinase-coupled receptor, and FAK and Src act immediately downstream of DCC in netrin signaling.
