Genome-wide mapping of SETMAR transposase binding sites in the human genome

Project description:SETMAR/Metnase is a naturally occurring fusion protein that consists of a histone-lysine methyltransferase domain and an HsMar1 transposase. To elucidate the biological role of SETMAR, it is crucial to identify genomic targets to which SETMAR specifically binds and link these sites to the regulation of gene expression. Herein, we mapped the genomic landscape of SETMAR in a near-haploid human leukemia cell line (HAP1) in order to identify on-target and off-target binding sites at high resolution and to elucidate their role in terms of gene expression. Our analysis revealed a perfect correlation between SETMAR and inverted tandem repeats (ITRs) of HsMar1 transposon remnants, which are considered as natural target sites for SETMAR chromosome binding. However, we did not detect any untargeted events at non-ITR sequences, calling into question previously proposed off-target binding sites. We identified sequence fidelity of the ITR motif as a key factor for determining the binding affinity of SETMAR for chromosomes, as higher ITR fidelity resulted in increased affinity for chromatin and stronger repression of SETMAR-bound gene loci. These associations highlight how SETMAR’s chromatin binding fine-tune gene regulatory networks in human tumour cells.

SETMAR methyl-lysine (3xMBT) pull-down

Project description:SILAC labeled HT-1080 cell lysate (K0R0 and K8R10) were treated with active or catalytic inactive SETMAR methyltransferase enzyme. Samples were combined and proteins modified by methyl-lysine enriched by 3xMBT. Quantitative comparison identified candidate proteins with increase methylation following incubation with SETMAR.

NONO mutations cause syndromic intellectual disability and inhibitory synaptic defects

Project description:Identifying causes of sporadic intellectual disability remains a considerable medical challenge. Here, we demonstrate that null mutations in the NONO gene, a member of the Drosophila Behavior Human Splicing (DBHS) protein family, are a novel cause of X-linked syndromic intellectual disability. Comparing humans to Nono-deficient mice revealed related behavioral and craniofacial anomalies, as well as global transcriptional dysregulation. Nono-deficient mice also showed deregulation of a large number of synaptic transcripts, causing a disorganization of inhibitory synapses, with impaired postsynaptic scaffolding of gephyrin. Alteration of gephyrin clustering could be rescued by over-expression of Gabra2 in NONO-compromised neurons. These findings link NONO to intellectual disability and first highlight the key role of DBHS proteins in functional organization of GABAergic synapses.

NONO knockdown RNA-seq and neuroblastoma PARCLIP analysis of NONO

Project description:siRNA knockdown of NONO mRNA followed by RNA-seq was carried out in the KELLY neuroblasotma cell line. In order to determine potential regulatory targets of NONO protein, we performed differential expression analysis. To identify the RNA targets of NONO in neuroblastoma, we carried out PAR-CLIP (Photoactivatable Ribonucleoside-Enhanced Crosslinking and Immunoprecipitation) using an antibody recognising NONO protein.
