Product Details

Brahma-related Gene 1 –mt (K798R, ATPase-deficient)

  • Species; Human
  • Expression Host: Baculovirus-insect cell
  • Tag: His-tag
  • Purity: 90%
  • Molecular Weight: 189.0 kDa.
  • Gene Accession Number: NM_003072.


Purification and Quality Control

The His-tag recombinant protein is purified by affinity chromatography in combination with FPLC columns.
The purified Brg1-mt(K798) is greater than 90% homogeneous based on SDS-PAGE analysis.

Unit Definition (Activity)

1 unit equals 1 nanogram purified protein. 50 - 100 units are required for an in vitro nucleosome remodeling assay and 100 units are required for a protein-protein interaction assay.

Applications

Recombinant BRG1 can be used 1) for protein-protein interaction assay; 2) for in vitro transcription assay; 3) for in vitro nucleosome remodeling assay; and 4) for cell growth assay.

Formulation and Storage

The protein is in 20mM Tris-HCl pH7.9,100mM NaCl, 0.2mM EDTA, 1mM DTT and 20% glycerol. Stored at -70°C before use. Avoid repeated freeze thaw cycles.

Synonym

Brahma-related Gene 1; BAF190; BRG1; FLJ39786; hSNF2b; RTPS2;SNF2; SNF2-BETA; SNF2L4; SNF2LB and SWI2.

Background

BRG1 is an essential component of the SWI/SNF chromatin remodeling complexes and is implicated in multiple functions through its interaction with different proteins, including the tumor suppressor protein pRb (Cat#P2007) (1), serine-threonine kinase LKB1 (2), and other transcription factors (3,4). Mutation of lysine to arginine at position 798 in the DNA-dependent ATPase domain of BRG1 a) failed to restore normal growth to swi2- cells (5), b) reduced its ability to repress c-fos transcription (6), and c) reduced CIITA (class II transactivator) induction and enhanced the rate of induction of the interferon-g-responsive GBP-1 gene (7).
