Identification of in vivo, conserved, TAF15 RNA binding sites and the impact of TAF15 on the neuronal transcriptome

ABSTRACT: TAF15, an RNA binding protein was recently implicated in Amyotrophic Lateral Sclerosis (ALS). ALS is a fatal neurodegenerative disease. We report the identification of the conserved neuronal RNA targets of TAF15 and the assessment of the impact of TAF15 depletion on the neuronal transcriptome. Our study uncovers regulation of splicing of sets of neuronal RNAs encoding proteins with essential roles in synaptic activities including glutamergic receptors such as zeta-1 subunit of the glutamate N-methyl-D-aspartate (NMDA) receptor (Grin1).

Distinct and shared functions of ALS-associated TDP-43, FUS, and TAF15 revealed by comprehensive multi-system integrative analyses [array]

Project description:TDP-43, FUS, and TAF15 are implicated in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia. We integrate CLIP-seq and RNA Bind-N-Seq technologies to discover that TAF15 binds to ~4,900 RNAs enriched for GGUA motifs. In the mouse brain, TAF15 and FUS, but not TDP-43, exhibit strikingly similar RNA binding profiles, yet they alter the expression of distinct mRNA populations upon their individual depletions. TAF15 has a minimal role in alternative splicing and instead affects RNA turnover, consistent with an enrichment of TAF15 binding sites in 3â untranslated regions. In human stem cell-derived motor neurons, loss of both TAF15 and FUS affected mRNAs distinct from those altered by loss of either protein alone, revealing redundant roles for TAF15 and FUS in maintaining mRNA levels. Furthermore, concomitant rather than individual depletion of TAF15 and FUS more closely resembles RNA profiles of motor neurons derived from FUS R521G ALS patients or from late-stage, sporadic ALS patients. Our study reveals convergent and divergent mechanisms by which FUS, TAF15 and TDP-43 affects RNA metabolism in neurological disease.

TAF15 amyloid filaments in neurodegenerative disease

Project description:Frontotemporal dementia (FTD) is the most common form of dementia after Alzheimer's disease and results from frontotemporal lobar degeneration (FTLD). The pathological hallmarks of FTLD are neuronal inclusions of specific, abnormally assembled proteins1. In the majority of cases, the inclusions contain amyloid filament assemblies of TAR DNA-binding protein 43 (TDP-43) or tau, with distinct filament structures characterising different FTLD subtypes2,3. The presence, identities and structures of amyloid filaments in the remaining ~10% of FTLD cases are unknown, but are widely believed to be composed of the protein fused in sarcoma (FUS). As such, these cases are commonly referred to as FTLD-FUS. Here, we used cryogenic electron microscopy (cryo-EM) to determine the structures of amyloid filaments extracted from the prefrontal and temporal cortices of four individuals with FTLD-FUS. Unexpectedly, we found abundant amyloid filaments of the FUS homologue TATA-binding protein-associated factor 15 (TAF15), rather than of FUS itself. The filament fold is formed from residues 7 to 99 in the low-complexity domain (LCD) of TAF15 and was identical between individuals. The formation of TAF15 amyloid filaments with a characteristic fold in FTLD establishes TAF15 proteinopathy in neurodegenerative disease. Furthermore, we found TAF15 filaments with the same fold in the motor cortex and brainstem of two of the individuals, who also showed changes associated with amyotrophic lateral sclerosis (ALS), suggesting that TAF15 proteinopathy may underlie a disease spectrum of FTLD and ALS. The structure of TAF15 amyloid filaments provides a basis for the development of model systems of neurodegenerative disease, as well as for the design of diagnostic and therapeutic tools targeting TAF15 proteinopathy.
