Abstract
Summary The processing of pre-mRNAs is a fundamental step required for the expression of most metazoan genes. Members of the family of serine/arginine (SR)-rich proteins are critical components of the machineries carrying out these essential processing events, highlighting their importance in maintaining efficient gene expression. SR proteins are characterized by their ability to interact simultaneously with RNA and other protein components via an RNA recognition motif (RRM) and through a domain rich in arginine and serine residues, the RS domain. Their functional roles in gene expression are surprisingly diverse, ranging from their classical involvement in constitutive and alternative pre-mRNA splicing to various post-splicing activities, including mRNA nuclear export, nonsense-mediated decay, and mRNA translation. These activities point up the importance of SR proteins during the regulation of mRNA metabolism.

Alternative pre-mRNA splicing regulation in cancer: pathways and programs unhinged

TL;DR: Emerging insights into this process indicate that pathways that are frequently deregulated in cancer often play important roles in promoting aberrant splicing, which in turn contributes to all aspects of tumor biology.

Complexity of the Alternative Splicing Landscape in Plants

TL;DR: Widespread changes in AS in response to developmental cues and stresses suggest a role for regulated splicing in plant development and stress responses, and new tools based on recent technological advances are allowing genome-wide analysis of RNA elements in transcripts and of chromatin modifications that regulate AS.

Mechanisms of Alternative Pre-Messenger RNA Splicing

TL;DR: This review describes what is currently known of the molecular mechanisms that control changes in splice site choice and starts with the best-characterized systems from the Drosophila sex determination pathway, and then describes the regulators of other systems about whose mechanisms there is some data.
