Sustained oscillations in the MAP kinase cascade.
The MAP kinase cascade is a network of enzymatic reactions arranged in layers. In each layer occurs a multiple futile cycle of phosphorylations. The fully phosphorylated substrate then serves as an enzyme for the layer below. This paper focusses on the existence of parameters for which Hopf bifurcations occur and generate periodic orbits. Furthermore it is explained how geometric singular pertu...
متن کاملReplicating the MAP Kinase Cascade in PEPA
Abstract. Ordinary Differential Equations (ODEs) represent a powerful technique for analysing biological systems. ODEs can cope with large numbers of components involved in multiple interactions. ODEs also bring a certain level of complexity through the reactions and the combinations of components within these reactions. Using the MitogenActivated Protein (MAP) Kinase cascade, it will be shown ...
متن کاملDystroglycan, a scaffold for the ERK-MAP kinase cascade.
Dystroglycan is an important cell adhesion receptor linking the actin cytoskeleton, via utrophin and dystrophin, to laminin in the extracellular matrix. To identify adhesion-related signalling molecules associated with dystroglycan, we conducted a yeast two-hybrid screen and identified mitogen-activated protein (MAP) kinase kinase 2 (MEK2) as a beta-dystroglycan interactor. Pull-down experiment...
متن کاملRas activation of the Raf kinase: tyrosine kinase recruitment of the MAP kinase cascade.
A continuing focus of our work has been an effort to understand the signal transduction pathways through which insulin achieves its cellular actions. In the mid-1970s, we and others observed that insulin promoted an increase in Ser/Thr phosphorylation of a subset of cellular proteins. This finding was unanticipated, inasmuch as nearly all of the actions of insulin then known appeared to result ...
متن کاملEffects of chronic social defeat stress on MAP kinase cascade.
Chronic psychological and social stress can cause psychiatric disorders in humans. In this study, we analyzed the mitogen-activated protein kinase (MAPK) cascade in the hippocampus of chronically socially defeated rats. The rats that were subjected to social defeat every day for 5 weeks showed physiological and behavioral changes, including a reduced rate of weight gain, enlarged adrenal glands...
