Gene Information

human ... SMARCA5(8467)

General description

SMARCA5 (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 5) is a mammalian homolog of ISW1, and forms the predominant catalytic ATPase subunit of SWI-type chromatin remodeling complexes. This gene is localized to human chromosome 4q31.1→q31.2, and encodes a protein composed of 1052 amino acids.

Western Blotting (1 paper)
Anti-SMARCA5 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

SMARCA5 (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 5) regulates the repair efficacy of transcription-hindering UV (ultraviolet) lesion, by promoting the interaction of CSB (Cockayne syndrome group B) to active TC-NER (transcription-coupled repair) complexes. This protein is associated with RNF168-dependent DNA damage signaling via DNA damage-mediated poly(ADP-ribosyl)ation.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.


Corresponding Antigen APREST70943.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide

Here, we first evaluated SMARCA5 expression and promoter DNA methylation in gastric carcinogenesis. Immunohistochemistry and methylation-specific PCR were analyzed in 19 and 48 normal mucosa and in 52 and 92 gastric cancer samples, respectively. We observed higher immunoreactivity of SMARCA5...

We have isolated a novel cDNA encoding a peptide with 86% sequence homology to hSNF2L protein, a previously isolated human homologue of Drosophila ISWI. This gene, designated SMARCA5, contained an open reading frame of 3,156 nucleotides encoding a 1,052 amino-acid...

Ionizing radiation (IR)-induced DNA double-strand breaks (DSBs) arising in native chromatin elicit an RNF8/RNF168-dependent ubiquitylation response, which triggers the recruitment of various repair factors. Precisely how this response is regulated in the context of chromatin remains largely unexplored. Here, we...
