However, some isoforms can not be revealed by the alignments, because the ESTs are incomplete. Fortunately, such isoforms may be obtained by a prediction tool. In this study, we built a system to detect splice sites in the genomic DNA and to generate all possible isoforms. To provide detailed view of the gene structures, we developed a database, namely ISOdb, which integrated the ProSplicer database to reveal the alternative splicing in human genome. By aligning ESTs, mRNA, and protein sequences to the genome sequences, we provide a web-based interface for users to retrieve all possible isoforms that include alignments of the ESTs and other information. http://140.115.50.96/isodb/ Keywords : isoform, alternative splicing(AS), splice sites en_US DC.subject 替代性剪接 zh_TW DC.subject 同形體 zh_TW DC.subject splice sites en_US DC.subject alternative splicing en_US DC.subject isoform en_US DC.title 以基因替代性剪接結構為基礎來建立基因同形體預測系統 zh_TW dc.language.iso zh-TW zh-TW DC.title A predictive system for gene isoforms based on alternative splicing variants and signals en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
