Subgroup G

Subgroup G: Spatial and Temporal Control of Cell Signaling

8:30 am – 12:30 pm, Room 113A
Organizers: Ivan Yudushkin, Medical University of Vienna; and Brendan D. Manning, T.H. Chan School of Public Health, Harvard

Supported by PicoQuant

Coordinated assembly, localization and regulation of enzymatic complexes shape cellular signaling responses to the environmental cues. To ensure the fidelity of these reactions, the cells need to precisely position the enzymes and their substrates at specific compartments and provide mechanisms to trigger and quench the enzymatic reactions in time. The details of the biochemical architecture and coupling between subcellular localization and regulation of signaling enzymes are not well understood.

The speakers of this Special Interest subgroup will present new methods for fast, high-resolution mapping, quantitation and modeling of cellular biochemical activities and discuss how dynamic architecture of enzymatic activities defines the adaptive character and fidelity of cellular responses.
