%X Compared to other subcellular organelles, centrosome proteome can hardly be studied, due to the dif- ficulties in separation and purification of centrosome. Auto-antisera from 6 autoimmune patients, which recognized centrosome specifically in immunofluorescence, were used to identify the corresponding centrosomal proteins. The sera were first tested by Western blot on whole cell lysate, and all bound antibodies were then eluted from each single band in Western blot membrane to assure which antibody was responsible for the centrosome specific immunofluorescence staining. The corresponding pro- teins were obtained by immunoprecipitation and identified by mass spectrometry. Six centrosomal proteins, including 2 known centrosomal proteins and 4 proteins with unknown localization or report- edly non-centrosomal localization, were identified. These proteins apparently involve in cell cycle regulation, signal transduction pathways, molecular chaperons, and metabolism enzymes, which may reflect the expected functional diversity of centrosome.
