The ubiquitination of proteins serves as targeting signals, making ubiquitinated proteins distributed to different parts of the cells, changing the activities, the interaction between macromolecules and the half-life of proteins. Therefore, ubiquitin conjugation is implicated in numerous metabolic processes in eukaryotes. Ubiquitin conjugates its protein substrates via a cascade reaction. This paper is a review of recent advances in this area.展开更多

Bioinformatics has become more important with the rapid accumulation of complete genome sequences and the advances of computational methods and related databases. The current computational approaches in promoter prediction, transcription factor binding site identification, composite elements prediction, co-regulation of gene expression analysis and phylogenetic footprinting in the regulatory region analysis are discussed in this review.展开更多
