Calendar Name: seminars Scheduled for: Monday, January 18 2010, 11:00 - 12:30 Event text: Prof Filip Rolland Laboratory of Functional Biology Plant Metabolic Signaling group Institute of Botany and Microbiology, K.U.Leuven BELGIUM Details: "Sensing and signaling plant carbon and energy status" ABSTRACT Plants are constantly challenged by changes in their environment that affect photosynthesis, respiration and carbon allocation and by a changing tissue- and developmental stage-dependent physiology during development. Therefore, they have evolved mechanisms to constantly monitor their metabolic status and adjust their growth accordingly. The KIN10/11 SnRK1 protein kinases, for example, function as conserved �fuel gauges� that trigger extensive metabolic reprogramming upon carbon and energy depletion, in part through a network of bZIP transcription factors. SnRK1 activity is controlled by the micromolar levels of trehalose-6-P (T6P), the metabolic intermediate of trehalose metabolism. While Arabidopsis does not accumulate this disaccharide, its genome encodes a large family of T6P synthase (TPS)-like and T6P phosphatase (TPP) proteins. Yeast functional complementation studies, however, suggest that most of the TPS-like proteins are catalytically inactive and expression studies reveal extensive regulation at the transcriptional level. Therefore, they might function as metabolic sensors of plant carbon status.

Calendar Name: seminars Scheduled for: Wednesday, December 16 2009, 15:00 - 16:30 Event text: Dr M. Madan Babu MRC Laboratory of Molecular Biology University of Cambridge UK Details: ABSTRACT Altered abundance of several intrinsically unstructured proteins (IUPs) has been associated with perturbed cellular signaling that may lead to pathological conditions such as cancer. Therefore, it is important to understand how cells precisely regulate the availability of IUPs. We observed that regulation of transcript clearance, proteolytic degradation, and translational rate contribute to controlling the abundance of IUPs, some of which are present in low amounts and for short periods of time. Abundant phosphorylation and low stochasticity in transcription and translation indicate that the availability of IUPs can be finely tuned. Fidelity in signaling may require that most IUPs be available in appropriate amounts and not present longer than needed.
