This book is intended to not only provide a broad perspective of recent progress in the field, but also to draw attention to some of the major questions that are currently under investigation, and also what we can anticipate learning from continued developments in the next several years of research. An important goal in splicing research is to understand the role of nuclear organization in the control of alternative splicing. The nucleus is divided into several subnuclear compartments and splicing occurs in only a subset of these locations. Moreover, nuclear organization can change in response to the activity of factors that are required to transcribe and splice a particular pre-mRNAs. Alternative Splicing in the Postgenomic Era serves as a valuable resource for both experts and non-experts alike. Research in the burgeoning field of alternative splicing in the postgenomic era is poised to uncover new and important aspects of gene regulation, as well as functions of the proteome.
