FUS Antibody (1120264)) [Unconjugated]

Western Blot shows lysates of Daudi human Burkitt's lymphoma cell line, K562 human chronic myelogenous leukemia cell line and MCF‑7 human breast cancer cell line. PVDF membrane was probed with 0.5 µg/ml of Mouse Anti-Human FUS Monoclonal Antibody (Catalog # MAB11793) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). Specific bands were detected for FUS at approximately 70 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

FUS was detected in immersion fixed paraffin-embedded sections of human testis using Mouse Anti-Human FUS Monoclonal Antibody (Catalog # MAB11793) at 5 µg/ml overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (VCTS021). Tissue was stained using the HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF007) and counterstained with hematoxylin (blue). Specific staining was localized to the nucleus.

A specific band was detected for FUS at approximately 101 kDa (as indicated) using both 2 µg/ml and 10 µg/ml of Mouse Anti-Human FUS Monoclonal Antibody (Catalog # MAB11793) followed by HRP-conjugated Goat Anti-Mouse Secondary Antibody (042-205). This experiment was conducted under reducing conditions and using the 12-230kDa separation system.

Background

Fused in sarcoma (FUS) is a multifunctional RNA-binding protein with a molecular weight of approximately 68 kDa. FUS belongs to the family of heterogeneous nuclear ribonucleoproteins (hnRNPs) and plays critical roles in RNA metabolism, including RNA splicing, transport, translation, and stability. Beyond its functions in RNA handling, FUS contributes to DNA damage repair and transcription regulation, highlighting its importance in cellular homeostasis. FUS is ubiquitously expressed across various tissues, with predominant localization in the nucleus; however, its mislocalization to the cytoplasm is directly implicated in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Mutations in the FUS gene have been identified as causative factors in familial ALS, where altered FUS protein function contributes to protein aggregation and neuronal toxicity. Additionally, FUS is involved in cellular stress responses, forming dynamic assemblies known as stress granules under adverse conditions. Aberrant FUS expression or activity has garnered attention as a key biomarker for neurodegenerative disorders and a promising target for therapeutic interventions.
