摘要: With the accomplishment of the genome draft sequences, identification of functional elements in genome has become an urgent task. Full-length cDNAs provide an important resource for gene identification and their precise structural feature determination. It also provides a basis for genomic element definition. As many regulatory elements are around transcription start sites (TSSs), precise localization of TSSs in the genome becomes a critical step for identifying the associated core promoters. Massive parallel snapshot of TSSs at a particular time under a specific experimental condition makes it possible to globally analyze important regulatory elements around TSSs and further construct transcriptional regulatory networks. In this paper, we first reviewed two important full-length cDNA cloning techniques: cap-trapper technique and oligo-capping technique. Then, we introduced deepCAGE, a cap-trapper and deep sequencing-based TSS profiling technique, and its applications in the research of transcriptional regulation.
