Spinal muscular atrophy (SMA) is a progressive neurodegenerative disease affecting lower motor neurons. SMA is caused by mutations in the Survival Motor Neuron 1 (SMN1) gene, which result in reduced levels of functional SMN protein. Biochemical studies have linked the ubiquitously expressed SMN protein to the assembly of pre-mRNA processing U snRNPs, raising the possibility that aberrant splicing is a major defect in SMA. Accordingly, several transcripts affected upon SMN deficiency have been re ...[more]

Trancriptional regulation by axonal SMN on motor neuron cells

Project description:Muscular atrophy (SMA) is an autosomal recessive disease causing selective motor neuron death by the loss of telomeric survival motor neuron gene, SMN1. Axonal SMN, a-SMN, is a truncated form of SMN, derived from an alternatively spliced SMN1 gene. (Setola, et. al. 2007 PNAS 104, 1959-1964). The cellular clones expressing a-SMN in a tetracycline-dependent manner were isolated from NSC34 by two-step stable transfection, first with the tetracycline-repressor construct and subsequently with the a-SMN cDNA. To identify novel a-SMN target genes, the transcriptome of several a-SMN clones was analyzed and compared with that of parental cells.

Mass spectrometry-based proteomic comparison of BirA-SMN, BirA-SMN-Y109C and BirA proxisomes.

Project description:Although recent advances in gene therapy provide hope for spinal muscular atrophy (SMA) patients, the pathology remains the leading genetic cause of infant mortality. SMA is a monogenic pathology that originates from the loss of the SMN1 gene in most cases or mutations in rare cases. Interestingly, SMN1 mutations occur broadly either within the TUDOR methyl-arginine (Rme) reader domain of SMN or its carboxy terminal oligomerization domain. We hypothesized that in SMN1 mutant cases, SMA may emerge from aberrant protein-protein interactions between SMN and key neuronal factors. Using a proximity-dependent biotinylation proteomic (BioID) approach, we have identified and validated a number of SMN-interacting proteins, including Fragile X mental retardation family members (FMRFM), such as FMRP itself as well as FXR1 and FXR2, some depending on a wild-type version of the TUDOR domain.

SMN and Symmetric Arginine Dimethylation of RNAP II CTD Control Termination

Project description:The C-terminal domain (CTD) of the RNA polymerase II (RNAPII) subunit POLR2A is a platform for modifications specifying the recruitment of factors that regulate transcription, mRNA processing, and chromatin remodeling. Here, we show that a CTD arginine residue (R1810 in human) that is conserved across vertebrates is symmetrically dimethylated (me2s). This R1810me2s modification requires Protein Arginine Methyltransferase 5 (PRMT5) and recruits the Tudor domain of the Survival of Motor Neuron (SMN) protein, which is mutated in spinal muscular atrophy (SMA). SMN interacts with Senataxin, which is sometimes mutated in Ataxia Oculomotor Apraxia 2 (AOA2) and Amyotrophic Lateral Sclerosis (ALS4). Because R1810me2s and SMN, like Senataxin, are required for resolving RNA-DNA hybrids, created by RNA polymerase II, that form â??R-loopsâ?? in transcription termination regions, we propose that R1810me2s, SMN, and Senataxin are components of a pathway for R-loop resolution in which defects can influence transcription termination and may contribute to neurodegenerative disorders. ChIP of RNAPII in Raji cells expressing shRNG against SMN or GFP; ChIP against RNAPII in Raji cells where endogenous RNAPII has been replaced with wt or R1810A mutant amanitin-resistant protein; and ChIP of SMN in HEK293 cells.

Neurochondrin interacts with the SMN protein suggesting a novel mechanism for Spinal Muscular Atrophy pathology.

Project description:Spinal Muscular Atrophy (SMA) is an inherited neurodegenerative condition caused by reduction in functional Survival Motor Neurones Protein (SMN). SMN has been implicated in transport of mRNA in neural cells for local translation. We previously identified microtubule-dependant mobile vesicles rich in SMN and SmB, a member of the Sm family of snRNP-associated proteins, in neural cells. By comparing the interactomes of SmB and SmN, a neural-specific Sm protein, we now show that the essential neural protein neurochondrin (NCDN) interacts with Sm proteins and SMN in the context of mobile vesicles in neurites. NCDN has roles in protein localisation in neural cells, and in maintenance of cell polarity. NCDN is required for the correct localisation of SMN, suggesting they may both be required for formation and transport of trafficking vesicles. NCDN may have potential as a therapeutic target for SMA together with, or in place of, those targeting SMN expression
