Title: Information Processing in Cellular Signaling
Signal or information processing and shaping of a response (a.k.a, signal transduction, regulation, sensing) is a common function performed by organisms on all levels of organization. In this talk, we will study information processing in cellular systems to answer questions like: Does the fidelity of information processing matter evolutionarily? What are the fundamental physical limits to the fidelity of information processing set by the intrinsic fluctuations in the cellular biochemical machinery? How close the cells come to these limits? What can they do to improve the performance? After introducing the general theoretical framework, we will address these and related questions in the specific experimental context of mammalian NF-kB signaling.
