CAGE Basic and Analysis Databases store an original resource produced by CAGE (cap-analysis gene expression; 1), which measures expression levels of transcription starting sites (TSS) by sequencing large amounts of transcript 5'-ends, termed CAGE tags. Millions of human and mouse high-quality CAGE tags derived from different conditions in over 20 tissues consisting of over 250 RNA samples are essential for identification of novel promoters and promoter characterization in the aspect of expression profile. CAGE Basic Database is a primary database of the CAGE resource, RNA samples, CAGE libraries, CAGE clone and tag sequences, etc. CAGE Analysis Database stores promoter related information, such as counts of related transcripts, CpG islands and conserved genome region. It also provides expression profiles at base pair and promoter levels. Both databases are based on the same framework, CAGE tag starting sites (CTSS), tag clusters (TC) for defining promoters, and transcriptional units (TU; 2). Their associations and TU attributes are available to find promoters of interest. These databases were provided for FANTOM3 (Functional Annotation Of Mouse 3; 3,4), an international collaboration research project focusing on expanding the transcriptome and subsequent analyses.
