Abnormality of the PBRM1 gene may be related to the occurrence of some GACs and can affect tumor immune activity, thereby affecting clinicopathology and prognosis. It may be a potentially effective predictive marker for immunotherapy and a novel therapeutic approach associated with synthetic lethality.

Using recombinant PBRM1 BD4 mutants, we have assessed how the most common missense mutations found in patients affect the stability and acetyllysine binding of PBRM1 BD4, revealing new insight into bromodomain structure and function. In addition we have expressed a subset of these PBRM1 missense mutations in renal cancer cell lines and assessed how they affect PBRM1 binding to acetyllysine substrates, and subsequent renal cancer growth.
