Abstract:
Nucleolus is the most prominent subnuclear structure, which performs a wide variety of functions in the eu-karyotic cellular processes. In order to understand the structural and functional role of the nucleoli in bovine cells,we analyzed the proteomie composition of the bovine nueleoli. The nucleoli were isolated from Madin Darby bo-vine kidney cells and subjected to proteomie analysis by LC-MS/MS after fractionation by SDS-PAGE and strongcation exchange chromatography. Analysis of the data using the Mascot database search and the GPM databasesearch identified 311 proteins in the bovine nucleoli, which contained 22 proteins previously not identified in theproteomic analysis of human nucleoli. Analysis of the identified proteins using the GoMiner software suggestedthat the bovine nueleoli contained proteins involved in ribosomal biogenesis, cell cycle control, transcriptional,translational and post-translational regulation, transport, and structural organization.
