WebNov 1, 2000 · Burge et al. ( 24) describe a method to classify splice sites based on the spliceosome machinery involved in their processing and suggest that such splice pairs as AT-AG or AT-AA could represent a transitional state between two splicing systems. However, no systematic analysis of all types of non-canonical splice sites has been … Eukaryotic genomes contain large numbers of splice sites, known as cryptic splice sites (css), which are generally held to be disadvantageous sites that are dormant or used only at low levels unless activated by mutation of nearby authentic or advantageous splice sites (1,2). Once activated, css may be used … See more The CSF program is designed to identify transcripts that are generated through the low level use of css by normal genes. In addition, CSF also identifies a subset of alternative splice sites that are similar to css, but are used at … See more Reserch grants from Biotechnology and Biosciences Research Council and Atazoa.
