Specificity / Sensitivity
ARID1A/BAF250A (E4F8T) Mouse mAb recognizes endogenous levels of total ARID1A/BAF250A protein. This antibody detects bands of unknown origin at 70 kDa and 100 kDa.
Species Reactivity:
Human, Rat, Monkey
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly149 of human ARID1A/BAF250A protein.
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).
ARID1A/BAF250A is one of the accessory subunits of the SWI/SNF complex that is an essential part of the esBAF (mouse embryonic stem cell specific SWI/SNF complex). ARID1A/BAF250A is critical for ES cell pluripotency and differentiation into mesoderm-derived cardiomyocytes and adipocytes (10). In addition, ARID1A/BAF250A has been found to be frequently mutated in several cancers such as uterine and ovarian endometrioid carcinoma and ovarian clear cell carcinoma (11-13).
