Anti-SETX / Senataxin

Adding 0.2 ml of distilled water will yield a concentration of 500 ug/ml. SETX antibody detects Senataxin, a nuclear RNA/DNA helicase involved in transcription termination, RNA processing, and DNA damage repair. Encoded by the SETX gene on chromosome 9q34.13, this large helicase contains a conserved C-terminal superfamily 1 (SF1) helicase domain that unwinds RNA/DNA hybrids (R-loops) formed during transcription and replication. By resolving R-loops, SETX maintains genomic stability and coordinates proper transcription termination for RNA polymerase II genes.Senataxin interacts with transcription termination factors, RNA-processing proteins, and DNA repair complexes to integrate transcriptional and genomic maintenance pathways. It facilitates the repair of transcription-associated DNA damage and supports RNA splicing fidelity by ensuring timely R-loop resolution. SETX localizes to nuclear foci associated with active transcription sites and DNA damage response regions.The SETX antibody is widely used in molecular genetics, neurobiology, and genome stability research to study helicase activity, R-loop metabolism, and transcriptional control. Western blot analysis identifies a 303 kilodalton band corresponding to Senataxin, while immunofluorescence reveals discrete nuclear foci marking transcriptionally active chromatin. This antibody supports investigations into RNA-DNA hybrid regulation and the prevention of replication stress.Mutations in SETX cause neurological disorders such as ataxia with oculomotor apraxia type 2 (AOA2) and amyotrophic lateral sclerosis type 4 (ALS4), highlighting its role in maintaining neuronal integrity. Dysfunctional Senataxin results in R-loop accumulation, transcriptional stress, and DNA strand breaks. The SETX antibody provides a reliable reagent for exploring the links between transcription, RNA metabolism, and neurodegeneration. NSJ Bioreagents supplies this antibody validated for its applications, ensuring reproducible detection in genome maintenance studies.
