The SMARCAL1 antibody targets SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily A-like protein 1, a nuclear enzyme encoded by the SMARCAL1 gene. This ATP-dependent annealing helicase plays a vital role in DNA replication and repair, particularly in stabilizing stalled replication forks and preventing genome instability. The SMARCAL1 antibody provides a crucial research tool for investigating how cells respond to replication stress and maintain chromatin integrity under challenging conditions.
SMARCAL1 is a member of the SNF2 family of chromatin remodelers, a large group of ATPases that modify DNA-protein interactions to facilitate replication and transcription. It is recruited to sites of replication fork arrest via interactions with replication protein A (RPA) and catalyzes branch migration to restart replication. This enzymatic process helps prevent double-strand breaks and genomic collapse. The SMARCAL1 antibody allows direct visualization of the protein in the nucleus, providing insight into its dynamics during S-phase and after genotoxic stress.
Mutations in SMARCAL1 are the primary cause of Schimke immuno-osseous dysplasia (SIOD), a rare autosomal recessive disorder marked by short stature, renal failure, and immune dysfunction. These phenotypes stem from impaired DNA repair and replication mechanisms, demonstrating the importance of SMARCAL1 in cellular viability and developmental stability. The SMARCAL1 antibody is therefore valuable not only in basic chromatin biology but also in studies of human disease and genomic maintenance.
SMARCAL1's helicase activity is regulated by phosphorylation events mediated by ATR kinase and other components of the DNA damage response. These modifications influence its recruitment and activity at stalled forks. Researchers use the SMARCAL1 antibody in combination with phospho-specific markers to map these regulatory pathways. Western blotting enables detection of total protein levels, while immunofluorescence and confocal microscopy reveal its nuclear localization and accumulation at replication foci. Chromatin immunoprecipitation using the SMARCAL1 antibody further allows identification of genomic sites directly bound by the enzyme, shedding light on its mechanistic involvement in replication restart.
In broader biological contexts, SMARCAL1 contributes to genome stability, epigenetic maintenance, and transcriptional regulation through chromatin remodeling. Its deficiency can cause widespread transcriptional dysregulation and heightened sensitivity to replication stress. The SMARCAL1 antibody supplied by NSJ Bioreagents is optimized for applications across molecular and cell biology platforms, providing a consistent reagent for elucidating the mechanisms that protect genome integrity. It is particularly useful for studies exploring interactions between SMARCAL1 and other chromatin remodelers, helicases, and DNA repair factors.
Ongoing research using the SMARCAL1 antibody continues to clarify how this enzyme coordinates DNA replication and repair, how its dysfunction leads to disease, and how it might be therapeutically targeted to enhance genome stability. The combination of functional versatility and high-quality specificity makes the SMARCAL1 antibody a key reagent for understanding the complex interplay between chromatin structure, replication stress, and genomic maintenance.
Optimal dilution of the SMARCAL1 antibody should be determined by the researcher.
E.coli-derived human SMARCAL1 recombinant protein (Position: M1-L782) was used as the immunogen for the SMARCAL1 antibody.
After reconstitution, the SMARCAL1 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
