Summary

Molecular mechanisms connecting signal transduction and pre-mRNA alternative splicing

Cellular processes are tightly regulated at different levels by various signaling pathways depending on extracellular stimulations. Extensive research over many years has identified numerous signaling pathways that influence the regulation of gene transcription and hence, it was thought, the fundamental properties of the cell.

More recently, it has been demonstrated that post-transcriptional gene regulation
is at least, and even possibly more, important than transcription regulation. However,
the main pathways governing regulation remain to be elucidated. For many years,
RNA molecules, especially messenger RNAs (mRNAs) were considered as passive
molecules. It is now clear that numerous RNA binding proteins play an important role
in many cellular functions. These proteins regulate gene expression at different levels. The main post-transcriptional gene regulation events include alternative splicing, RNA export and stability and translation of mRNAs.

Alternative splicing

In eukaryotes, gene transcription produces a pre-messenger RNA (pre-mRNA) that
contains alternating sequences, the introns and the exons. Constitutive splicing
consists of removing the introns from the pre-mRNA and joining the exons producing a mature mRNA. This event is catalyzed by a large macromolecular complex, the
spliceosome, that specifically recognizes splice sites, the conserved nucleotide
sequences that comprise exon/intron junctions. However, splicing can lead to many
different mRNAs from a single pre-mRNA. This process is called alternative splicing.
Alternative splicing describes the regulated process of differential inclusion or
exclusion of certain regions of the pre-mRNA. This process allows the production, from a single gene, of many protein isoforms that can have different cellular functions. Alternative splicing is thus an important source of protein diversity from a limited number of genes. Recently, it was shown that more than 90% of the protein-coding genes in the human genome undergo alternative splicing.

Alternative splicing


Alternative splicing is possible because eukaryotic pre-mRNAs possess multiple potential splice sites. Some are located at the exon/intron junctions and are used during constitutive splicing. Many others are located in exons and introns and are recognized by the spliceosome only under certain conditions. The use of a splice site depends on the recognition of the pre-mRNA by specific RNA binding proteins, the splicing factors. These proteins recognize specifically short RNA sequences, the cis-acting elements, which are generally located near splice sites. The binding of splicing factors to these cis-acting elements affects the use of nearby splice sites.

Current views suggest that numerous splicing factors may compete to enhance or
inhibit the use of a specific splice site. Alternative splicing regulation is therefore often modulated by the relative concentrations of these splicing factors in the nucleus. This modulation is achieved by different manners: some splicing factors may be expressed only at certain stages of the development or only in specific tissues. Alternatively, the nuclear localization of these splicing factors can be regulated by post-translational modifications, such as phosphorylation, that affect the distribution of these factors between the nucleus and the cytoplasm. As a consequence, many specific protein isoforms are produced by alternative splicing either in certain developmental stages or tissues, or as a consequence of regulation by extracellular signaling mechanisms.

The relationship between signaling pathways and post-transcriptional gene regulation, however, is still poorly understood.

Research interests

Our main research interest is therefore to understand at the molecular level the interplay between signaling pathways and post-transcriptional gene regulation. To this aim, we are studying protein-protein and protein-RNA complexes using structural biology techniques (NMR and X-ray) and biophysical methods (isothermal titration calorimetry, ITC).

In addition, our structural work is complemented by functional assays thank to collaboration with the group of Professor Ian Eperon within the department of Molecular and Cellular Biology.
