Abstract

The construction and analysis of protein databases using the QUEST system is described, and the REF52 protein database is presented. A protein database provides the means to store and compare quantitative and descriptive data for up to 2000 proteins from many experiments that employ computer-analyzed two-dimensional gel electrophoresis. The QUEST system provides the tools to manage, analyze, and communicate these data. The REF52 database contains experiments with normal and transformed rat cell lines. In this report, many of the proteins on the REF52 map are identified by name, by subcellular localization, and by mode of post-translational modification. The quantitative experiments analyzed and compared here include 1) a study of the quantitative reproducibility of the analysis system, 2) a study of the clonal reproducibility of REF52 cells, 3) a study of growth-related changes in REF52 cells, and 4) a study of the effects of labeling cells for varying lengths of time. Of the proteins analyzed from REF52 cells, 10% are nuclear, 6% are phosphoproteins, and 4% are mannose-labeled glycoproteins. The mannose-labeled proteins are more prominent in patterns from quiescent cells, while the synthesis of cytoskeletal proteins is generally repressed at quiescence. A small set of proteins, selected for elevated rates of synthesis is generally repressed at quiescence. A small set of proteins, selected for elevated rates of synthesis in quiescent versus proliferating cells includes one of the tropomyosin isoforms, a myosin light chain isoform, and several prominent glycoproteins. These proteins are thought to be characteristic of the differentiated state of untransformed REF52 cells. Proteins induced early versus late after refeeding quiescent cells show very different patterns of growth regulation. These studies lay the foundations of the REF52 database and provide information needed to interpret the experiments with transformed REF52 cells, which are reported in the accompanying paper (Garrels, J., and Franza, B. R., Jr. (1989) J. Biol. Chem. 264, 5299-5312).
