In the next 5 years of the NURSA project, we will carry out a series of advanced data acquisitions that willprovide a proteomic atlas for the 'systems biology' of signal-regulated NR pathways in vivo. Such highthroughputdata acquisition projects are not themselves possible as R01 mechanisms, yet the accumulateddata will greatly stimulate hypothesis-driven research in the entire field of nuclear receptor science. We willpursue the isolation and identification of coregulator (CoR) complexes in mouse tissues, improving protocolsFor generating protein extracts from mouse tissues of liver, adipocytes, uterus and brain for proteomicanalyses, and isolating and identify coregulator protein complexes from mouse tissues for analysis by massspec. We will carry out profiling of post-translational modifications (PTM) of coregulator complexes and wewill also profile coordinated PTMs of NR and CoRs following physiologic signaling.
