    Protocol

    Specificity / Sensitivity

    Phospho-PBRM1/BAF180 (Ser948) (E6Z2C) Rabbit mAb recognizes endogenous levels of PBRM1/BAF180 protein only when phosphorylated at Ser948. This antibody detects a band at 260 kDa of unknown origin.

    Species Reactivity:

    Human, Mouse

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser948 of human PBRM1/BAF180 protein.

    Background

    ATP-dependent chromatin remodeling complexes play an essential role in the regulation of various nuclear processes, such as gene expression, DNA replication, and repair (1,2). The SWI/SNF chromatin remodeling complex consists of more than 10 subunits with a single molecule of the ATPase catalytic subunit BRM or BRG1, but not both. The activities of these two subunits drive the disruption of histone-DNA contacts that lead to changes in accessibility of crucial regulatory elements within chromatin (2-5). The BRM/BRG1 containing SWI/SNF complexes are recruited to target promoters by transcription factors, such as nuclear receptors, p53, RB, and BRCA1 to regulate gene activation, cell growth, the cell cycle, and differentiation processes (1,6-9).

    PBRM1/BAF180 is a unique member of the SWI/SNF complex PBAF, which binds to kinetochores in mitotic chromatin (10,11). PBAF is involved in nuclear receptor-mediated transcription and retinoic acid driven gene activation (12,13). PBRM1/BAF180 has been shown to be a potent tumor suppressor, as it is the second-most mutated gene in renal carcinomas (14). Mutations of PBRM1/BAF180 have also been shown to be involved in breast cancer, and low expression relates to poorer prognosis (15,16). PBRM1/BAF180 is phosphorylated at Ser948 by ATM during DNA damage, which is important for transcriptional silencing and repair around double-stranded breaks (17).
