概要

Post-translational modifications regulate various properties of proteins such as their activity, localization, stability, and interactions with other molecules, thereby playing a key role in the control of cell signaling networks and diverse biological processes. Recent advances in mass spectrometry, and in molecular, structural, and mathematical biology, have not only made it possible to identify novel post-translational modifications, but have also opened the door to a comprehensive understanding of the molecular basis and dynamics of protein modifications. It is now appreciated that spatio-temporal changes in post-translational modifications serve as the driving force in the dynamics of signal transduction pathways and underlie the diversity of cell responses. Furthermore, functional interplay between different modifications has recently been identified and is important for dictating cell-fate decisions. Perturbation of post-translational modifications is involved in a variety of life-threatening diseases. Therefore these modifications are also of clinical importance. In this workshop, speakers from various fields of biology, including molecular, structural, and mathematical biology, will present recent advances in the understanding of post-translational modifications (e.g. ubiquitination, sumoylation, glycosylation, acetylation, and phosphorylation) that regulate critical signaling pathways (e.g. NF-κB, MAPK, and Notch signaling). Furthermore, the use of an interdisciplinary approach to study signal transduction networks will be discussed.
