The FUS gene encodes the Fused in Sarcoma (FUS) protein, also known as Translocated in Liposarcoma (TLS). As an RNA-binding protein, FUS regulates pre-mRNA splicing, mRNA transport, and translational processes, interacting with core RNA processing machinery to maintain cellular RNA homeostasis. It integrates into pathways governing gene expression and stress response.
Mutations in FUS are associated with amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and liposarcoma. For ALS/FTD, drug development targets FUS aggregation— a key pathogenic event— using small molecules that inhibit misfolding or RNA interference to reduce toxic protein levels, though most candidates are in preclinical or early clinical phases.

IHC image of CSB-RA796544A0HU diluted at 1:100 and staining in paraffin-embedded human glioma cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB.

Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB.
Immunofluorescence staining of SH-SY5Y cell with CSB-RA796544A0HU at 1:50, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
Overlay Peak curve showing SH-SY5Y cells stained with CSB-RA796544A0HU (red line) at 1:100. The cells were fixed in 4% formaldehyde and permeated by 0.2% TritonX-100 for 10min. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/1*106cells) for 45min at 4℃. The secondary antibody used was FITC-conjugated goat anti-rabbit IgG (H+L) at 1/200 dilution for 35min at 4℃.Control antibody (green line) was Rabbit IgG (1ug/1*106cells) used under the same conditions. Acquisition of >10,000 events was performed.
