Recombinant Human RNA-binding protein FUS (FUS)

1. loss of nuclear FUS caused DNA nick ligation defects in motor neurons. PMID: 30206235
2. The herein presented data uncover a novel mechanism by which the fusion oncogene FUS-CHOP actively promotes invasion in myxoid and round cell liposarcoma through the activation of a SRC/FAK/RHO/ROCK signaling axis. PMID: 29190494
3. When FUS was overexpressed and then de novo synthesis was blocked with ActD, the decay rate of LATS1/2 was slower in the FUS-overexpressed cells than in control cells. PMID: 30308519
4. Motor neuron cultures exposed to mutant FUS (mutFUS)conditioned medium (ACM), but not wild-type FUS ACM, undergo significant cell loss, which is preceded by progressive degeneration of neurites. We found that Tumor TNFalpha is secreted into ACM of mutFUS-expressing astrocytes. Accordingly, mutFUS astrocyte-mediated motor neuron toxicity is blocked by targeting soluble TNFalpha with neutralizing antibodies. PMID: 29380416
5. the abnormal stable complex of FUS-R521C/PRMT1/Nd1-L mRNA could contribute to neurodegeneration upon oxidative stress. PMID: 28094300
6. more selective group of neurons appears to be affected in frontotemporal lobar degeneration (FTLD)-TDP and FTLD-FUS than in FTLD-tau PMID: 28984110
7. Taken together, FUS RNA-recognition motif appears to play a crucial role in exaggerating the physiological/reversible self-assembly into pathological/irreversible fibrillization, thus contributing to manifestation of FUS cytotoxicity. PMID: 28432364
8. Fus is a binding partner of FMRP. PMID: 28424484
9. Study demonstrates that FUS mutants, but not WT forms, impair fast axonal transport (FAT) in brain tissue of patients with ALS, through a mechanism dependent on activation of p38 MAPK. PMID: 28273913
10. In human stem cell-derived motor neurons, the RNA profile associated with concomitant loss of both TAF15 and FUS resembles that observed in the presence of the amyotrophic lateral sclerosis (ALS)-associated mutation FUS R521G, but contrasts with late-stage sporadic ALS patients. PMID: 27378374
11. FUS P525L mutation alters transcriptome and microRNA pathways in motor neurons with implications for ALS pathogenesis. PMID: 28988989
12. This study showed that in fibroblasts of FUS P525L mutation carriers, FUS mislocalized to the cytoplasm where it redistributed into stress granules with likely a dose effect. PMID: 29035885
13. Results find that mutant but not wild-type FUS decreased dendritic growth, mRNA levels, and protein synthesis in dendrites. These data suggest that cytoplasmic FUS aggregates trap mRNA and its transporters, impairing dendritic mRNA trafficking and translation, in turn leading to the disruption of dendritic homeostasis and the development of frontotemporal dementia phenotypes. PMID: 28928015
14. activation of the IGF-IR/PI3K/Akt signaling system is a common pattern in MLS which appears to be transcriptionally controlled, at least in part by induction of IGF2 gene transcription in a FUS-DDIT3-dependent manner. PMID: 28637688
15. SOD1 mutations were present in 20% of familial amyotrophic lateral sclerosis (ALS) patients and 1.9% of sporadic ALS patients, while FUS mutations were responsible for 13.3% of familial ALS cases, and TARDBP mutations were rare in either familial or sporadic ALS cases. PMID: 27604643
16. Depletion of SAFB1 reduced FUS's localization to chromatin-bound fraction and splicing activity, suggesting SAFB1 could tether FUS to chromatin compartment thorough N-terminal DNA-binding motif. Moreover, FUS interacts with another nuclear matrix-associated protein, Matrin3. PMID: 27731383
17. A molecular docking and dynamics study concluded that R521C and R521H mutations in FUS result in weak binding with Karyopherin-beta2 leading to amyotrophic lateral sclerosis. PMID: 27381509
18. both FUS and TDP43 colocalize with active RNA polymerase II at sites of DNA damage along with the DNA damage repair protein, BRCA1, and FUS and TDP43 participate in the prevention or repair of R loop-associated DNA damage, a manifestation of aberrant transcription and/or RNA processing PMID: 27849576
19. FUS mutations were significantly more common among mainland Chinese patients than those among Caucasian populations (p=6.8x10-3). The high frequency of FUS mutations in FALS and SALS in mainland China is another genetic feature distinct from Caucasians. PMID: 26519472
20. The impairment of PARP-dependent DNA damage response (DDR) signaling due to mutations in the FUS nuclear localization sequence induces additional cytoplasmic FUS mislocalization which in turn results in neurodegeneration and FUS aggregate formation in amyotrophic lateral sclerosis. PMID: 29362359
21. ALS-associated mutations enhance FUS protein propagation in Drosophila neurons. PMID: 28429234
22. juvenile ALS linked to FUS mutations represent a specific entity different from both classical juvenile ALS and adult ALS linked to FUS gene PMID: 28054830
23. Motor neurons expressing FUS with the P525L or the R521H mutation showed cytoplasmic mislocalization of FUS, hypoexcitability, and axonal transport defects. PMID: 29021520
24. Results suggest that RBM45 serves as a negative regulator to prevent FUS-mediated excessive recruitment of HDAC1 to the sites of DNA damage. PMID: 29140459
25. The review describes the main physiological functions of FUS and considers evidence for each of the theories of amyotrophic lateral sclerosis pathogenesis. PMID: 28707655
26. Authors used solid-state nuclear magnetic resonance methods to characterize the molecular structure of self-assembling fibrils formed by the LC domain of the fused in sarcoma (FUS) RNA-binding protein. From the 214-residue LC domain of FUS (FUS-LC), a segment of only 57 residues forms the fibril core, while other segments remain dynamically disordered. PMID: 28942918
27. Nuclear magnetic resonance spectroscopy demonstrates the intrinsically disordered structure of FUS's nearly uncharged, aggregation-prone, yeast prion-like, low sequence-complexity domain is preserved after phosphorylation. PMID: 28790177

30. FUS-induced reductions to ER-mitochondria associations and are linked to activation of glycogen synthase kinase-3beta (GSK-3beta), a kinase already strongly associated with ALS/FTD. PMID: 27418313
31. Motor-neuron disease (MND)-linked RNA-binding proteins (RBPs), TDP-43, FUS, and hnRNPA2B1, bind to and induce structural alteration of UGGAAexp. These RBPs suppress UGGAAexp-mediated toxicity in Drosophila by functioning as RNA chaperones for proper UGGAAexp folding and regulation of pentapeptide repeat translation. PMID: 28343865
32. we analyzed fast axonal transport in larval motor neurons of Drosophila models of TARDBP (TDP-43), FUS and C9orf72. We also analyzed the effect of loss-of-function mutants of the Drosophila orthologs of TDP-43 and FUS, TBPH and caz, respectively. The motor activities of larvae and adults in these models were assessed to correlate potential defects in axonal transport with locomotor deficits PMID: 27056981
33. These findings suggest a possible pathomechanism for amyotrophic lateral sclerosis in which mutated FUS inhibits correct splicing of minor introns in mRNAs encoding proteins required for motor neuron survival. PMID: 27252488
34. This study revealed a characteristic phenotype in FUS/TLS-linked FALS patients in Japan. PMID: 26823199
