This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The goal of this collaboration is to identify proteins that are new putative interactors of the p53 tumor suppressor protein. The input material for MudPIT analyzis is generated by tandem affinity purification starting with whole cell lysates. These lysates originate from breast cancer cells conditionally overexpressing TAP tagged p53. Furthermore these cells were treated with DNA damaging agents or c-MYC oncogene was overexpressed prior to TAP purification. The outcome should reflect the spectra of p53 associated proteins as they occur under different conditions of cellular stress.
