Research Abstract

It is well known that cells expresses various responses to extracellular stimuli, but these mechanisms in which distinct stimuli induces specific response remained poorly understood. To resolve this essential issue concerning signal transduction, I established the system for large scale identification and quantification of protein phosphorylations. Using this system, I obtained quantitative time-resolved information about more than 25,000 phosphorylation sites from several cell lines which were treated with various stimulants.
