Nuclear Rna Processing

Nuclear RNA processing is a critical stage in eukaryotic gene expression, and is controlled in part by the expression and concentration of nuclear RNA-binding proteins. Different nuclear RNA-binding proteins are differentially expressed in different cells, helping the spliceosome to decode pre-mRNAs into alternatively spliced mRNAs. Recent post-genomic technology has exposed the complexity of nuclear RNA processing, and is starting to reveal the mechanisms and rules through which networks of RNA-binding proteins can regulate multiple parallel pathways. Identification of multiple parallel processing pathways regulated by nuclear RNA-binding proteins is leading to a systems-wide understanding of the rules and consequences of alternative nuclear RNA processing.

Lateral Sclerosis

Amyotrophic Lateral Sclerosis (ALS) is an adult onset neurodegenerative disease, which is universally fatal. While the causes of this devastating disease are poorly understood, recent advances have implicated RNA-binding proteins (RBPs) that contain predicted prion domains as a major culprit. Specifically, mutations in the RBPs TDP-43 and FUS can cause ALS. Cytoplasmic mislocalization and inclusion formation are common pathological features of TDP-43 and FUS proteinopathies. Though these RBPs share striking pathological and structural similarities, considerable evidence suggests that the ALS-linked mutations in TDP-43 and FUS can cause disease by disparate mechanisms. In a recent study, Couthouis et al. screened for protein candidates that were also involved in RNA processing, contained a predicted prion domain, shared other phenotypic similarities with TDP-43 and FUS, and identified TAF15 as a putative ALS gene. Subsequent sequencing of ALS patients successfully identified ALS-linked mutations in TAF15 that were largely absent in control populations. This study underscores the important role that perturbations in RNA metabolism might play in neurodegeneration, and it raises the possibility that future studies will identify other RBPs with critical roles in neurodegenerative disease.

Shed Light

The long non-coding RNA Malat1 has been implicated in several human cancers, while the mechanism of action is not completely understood. As RNAs in cells function together with RNA-binding proteins (RBPs), the composition of their RBP complex can shed light on their functionality. We here performed quantitative interactomics of 14 non-overlapping fragments covering the full length of Malat1 to identify possible nuclear interacting proteins. Overall, we identified 35 candidates including 14 already known binders, which are able to interact with Malat1 in the nucleus. Furthermore, the use of fragments along the full-length RNA allowed us to reveal two hotspots for protein binding, one in the 5′-region and one in the 3′-region of Malat1. Our results provide confirmation on previous RNA-protein interaction studies and suggest new candidates for functional investigations.

Nuclear Rna Processing

We have identified a novel high molecular weight, vesicle-associated protein (VAP-1) in the eggs of the sea urchin Strongylocentrotus purpuratus. Biochemical fractionation and immunofluorescence analysis of unfertilized eggs indicate that VAP-1 is a peripheral membrane protein associated with microsomal membrane fractions. Sequence analysis of partial VAP-1 cDNA clones reveals that the protein contains at least four RNA-binding consensus sequences. The RNA-binding sequences are separated by several glycine rich domains and this organization, RNA-binding domains separated by glycine rich sequences, is common to several RNA-binding proteins including the heterogeneous ribonuclear protein A1 and nucleolin. The characteristics of VAP-1 suggest that the protein may function as a multidomain RNA-binding protein. The possibility that VAP-1 may play a role in nuclear RNA processing is also discussed.
