Searching across hundreds of databases
CCAAT/Enhancer Binding Proteindelta (C/EBPdelta) is a member of the highly conserved C/EBP family of leucine zipper (bZIP) proteins. C/EBPdelta is highly expressed in G0 growth arrested mammary epithelial cells (MECs) and "loss of function" alterations in C/EBPdelta have been associated with impaired contact inhibition, increased genomic instability and increased cell migration. Reduced C/EBPdelta expression has also been reported in breast cancer and acute myeloid leukemia (AML). C/EBPdelta functions as a transcriptional activator, however, only a limited number of C/EBPdelta target genes have been reported. As a result, the role of C/EBPdelta in growth control and the potential mechanisms by which "loss of function" alterations in C/EBPdelta contribute to tumorigenesis are poorly understood. The goals of the present study were to identify C/EBPdelta target genes using Chromatin Immunoprecipitation coupled with a CpG Island (HCG12K) Array gene chip ("ChIP-chip") assay and to assess the expression and potential functional roles of C/EBPdelta target genes in growth control.

View all literature mentionsHarvester is a Web-based tool that bulk-collects bioinformatic data on human proteins from various databases and prediction servers. It is a meta search engine for gene and protein information. It searches 16 major databases and prediction servers and combines the results on pregenerated HTML pages. In this way Harvester can provide comprehensive gene-protein information from different servers in a convenient and fast manner. As full text meta search engine, similar to Google trade mark, Harvester allows screening of the whole genome proteome for current protein functions and predictions in a few seconds. With Harvester it is now possible to compare and check the quality of different database entries and prediction algorithms on a single page.
