After transcription in the nucleus, RNA binding proteins (RBPs)
recognize cis-regulatory RNA elements within pre-mRNA sequence to
form mRNA-protein (mRNP) complexes. Similarly to DNA binding
proteins such as transcription factors that regulate gene
expression by binding to DNA elements in the promoters of genes,
RBPs regulate the fate of target RNAs by interacting with specific
sequences or RNA secondary structural features within the
transcribed RNA molecule. The set of functional RNA elements
recognized by RBPs within target RNAs and which control the
temporal, functional and spatial dynamics of the target RNA define
a putative mRNP code . These cis-regulatory RNA elements can be
found in the 5 and 3 untranslated regions (UTRs), introns, and
exons of all protein-coding genes. RNA elements in 5 and 3 UTRs are
frequently involved in targeting RNA to specific cellular
compartments, affecting 3 end formation, controlling RNA stability
and regulating mRNA translation. RNA elements in introns and exons
are known to function as splicing enhancers or silencers during the
splicing process from pre-mRNA to mature mRNA.
This book provides case studies of RNA binding proteins that
regulate aspects of RNA processing that are important for
fundamental understanding of diseases and development. Chapters
include systems-level perspectives, mechanistic insights into RNA
processing and RNA Binding proteins in genetic variation,
development and disease. The content focuses on systems biology and
genomics of RNA Binding proteins and their relation to human
diseases."
