In this context, we have identified microcompartmentation of
signaling complexes in the plasma membrane and in endosomes as important determinants for receptor dynamics and signaling activity.
Control of T cell signaling occurs through both positive and negative regulation, as well as through the actions of molecular scaffolds that contribute to the formation
of signaling complexes.
Binding to the family of NOD - like receptors triggers the assembly of large
protein signaling complexes called inflammasomes, leading infected cells to die and produce inflammatory mediators.
To study an even
larger signaling complex surrounding the switch, the team is expanding these simulations on the 27 - petaflop, CPU — GPU machine Titan — the nation's most powerful supercomputer, managed by the Oak Ridge Leadership Computing Facility at ORNL.
In this study, scientists have found that a component of the system, HOIL - 1L, is necessary for formation of the NLRP3 - ASC
inflammasome signaling complex.
Her previous work identified the scaffold protein p62 as a critical component of the mTORC1 nutrient -
sensing signaling complex.
We therefore study functions of kinetochore proteins and spatio - temporal control of kinase /
phosphatase signaling complexes, in particular those involved in attachment error - correction and the spindle assembly checkpoint.
To achieve this goal, we developed an integrated system that enables simultaneous real - time visualization of structural reorganization in spatially -
restricted signaling complexes and functional modifications of single synapses in brain circuits.
One began when University of Michigan biochemist Roger Sunahara and Stanford researcher Brian Kobilka asked Skiniotis to help characterize the structure of an activated G protein coupled receptor (GPCR) bound to a G protein trimer, a
central signaling complex involved in all aspects of human physiology.
For example, when biting into an apple, the body will
immediately signal a complex sequence of messages and processes to break down the apple into energy and essential structural nutrients for cellular repair and replacement.
The proteins newly revealed to be druggable belong to a variety of functional classes, including enzymes that catalyze biochemical reactions, scaffold proteins that act as hubs for other
protein signaling complexes, and transcription factors that regulate gene activity.
«This is the first time that this specific protein - protein
signaling complex has been identified in GBM, and it gives us a new potential target for drug development,» says Fisher, Thelma Newmeyer Corman Endowed Chair in Cancer Research and co-leader of the Cancer Molecular Genetics research program at VCU Massey, professor and chair of the Department of Human and Molecular Genetics at the VCU School of Medicine, and director of the VIMM.
Dimers are grouped in threes to form larger units of
the signaling complex, called trimers of dimers.
Unravel the mechanistic role of the associated Janus kinases in the assembly of
the signaling complex.
Danish artist Julie Sass presents a cohesive body of new work as part of Copenhagen Arts Week that
signals complex, painterly explorations in abstract minimalism
