Supplementary information

PBRM1 also known as BAF180 is an important component of the SWI/SNF chromatin remodeling complex. It has a molecular weight of approximately 187 kDa. Within the cell PBRM1 is expressed in various tissues but shows higher expression in kidney and breast tissues. Its role involves binding to acetylated histones which influences chromatin structure and gene expression regulation.
Biological function summary

The PBRM1/BAF180 protein functions as part of the SWI/SNF complex which includes the catalytic subunit BRG1 or BRM. This complex is important for altering chromatin architecture which regulates access of transcriptional machinery to DNA. It plays a significant role in the control of cell growth and differentiation processes. The structural integrity of PBRM1 is necessary for the functionality of the SWI/SNF complex.

Pathways

PBRM1/BAF180 is an important player in pathways involving chromatin remodeling and transcriptional regulation. It is implicated in the WNT signaling pathway interacting with proteins such as β-catenin to influence gene transcription. It also partakes in the p53 pathway where it contributes to the regulation of cell cycle and apoptosis by modulating p53 activity.

Mutations in PBRM1 are frequently observed in renal cell carcinoma. Its disruption affects chromatin remodeling which disrupts normal gene expression contributing to cancer progression. PBRM1 also relates to breast cancer where alterations can promote tumor formation. In these contexts the interaction of PBRM1 with other proteins like VHL in renal carcinoma helps elucidate its role in tumor suppression and development.
