Protocols

Specificity / Sensitivity

SMARCC1/BAF155 (D7F8S) Rabbit mAb recognizes endogenous levels of total SMARCC1/BAF155 protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly975 of human SMARCC1/BAF155 protein.

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using SMARCC1/BAF155 (D7F8S) Rabbit mAb.

IP

IP

Immunoprecipitation of SMARCC1/BAF155 from HeLa cell extracts using Rabbit (DA1E) mAb IgG XP® Isotype Control #3900 (lane 2) or SMARCC1/BAF155 (D7F8S) Rabbit mAb (lane 3). Lane 1 is 10% input. Western blot analysis was performed using SMARCC1/BAF155 (D7F8S) Rabbit mAb.

Chromatin IP

Chromatin IP

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 MCF7 cells, grown in phenol red-free medium and 5% charcoal-stripped FBS for 4 d followed by treatment with β-estradiol (10 nM, 45 min), and either 5 μl of SMARCC1/BAF155 (D7F8S) Rabbit mAb or 2 μl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using SimpleChIP® Human ESR1 Promoter Primers #9673, SimpleChIP® Human pS2 Promoter Primers #9702, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.


Background

ATP-dependent chromatin remodeling complexes play an essential role in the regulation of nuclear processes such as transcription and DNA replication and repair (1,2). The SWI/SNF chromatin remodeling complex consists of more than 10 subunits and contains a single molecule of either BRM or BRG1 as the ATPase catalytic subunit. The activity of the ATPase subunit disrupts histone-DNA contacts and changes the accessibility of crucial regulatory elements to the chromatin. The additional core and accessory subunits play a scaffolding role to maintain stability and provide surfaces for interaction with various transcription factors and chromatin (2-5). The interactions between SWI/SNF subunits and transcription factors, such as nuclear receptors, p53, Rb, BRCA1, and MyoD, facilitate recruitment of the complex to target genes for regulation of gene activation, cell growth, cell cycle, and differentiation processes (1,6-9).

SMARCC1/BAF155 is one of the core subunits of the SWI/SNF complex, which is necessary for efficient nucleosome remodeling by BRG1 in vitro (10). SMARCC1 is an essential part of the mouse embryonic stem cell specific SWI/SNF complex (esBAF), which is necessary for early embryogenesis, especially proper brain and visceral endoderm development (11-13).
