Relating alternative splicing to proteome complexity and genome evolution.
Prior to genomics, studies of alternative splicing primarily focused on the function and mechanism of alternative splicing in individual genes and exons. This has changed dramatically since the late 1990s. High-throughput genomics technologies, such as EST sequencing and microarrays designed to detect changes in splicing, led to genome-wide discoveries and quantification of alternative splicing in a wide range of species from human to Arabidopsis. Consensus estimates of AS frequency in the human genome grew from less than 5% in mid-1990s to as high as 60-74% now. The rapid growth in sequence and microarray data for alternative splicing has made it possible to look into the global impact of alternative splicing on protein function and evolution of genomes. In this chapter, we review recent research on alternative splicing's impact on proteomic complexity and its role in genome evolution.
