BAP1 and nonpapillary renal cell carcinoma: Furthermore, decreased SRC Y527 phosphorylation was also observed in cell lines reconstituted with the wild-type form of BAP1 but not in those expressing the catalytically inactive BAP1 p.C91S (Figure 1C,D and S1D), similar to the pattern observed in RPPA data from both UM (Figure 1B) and ccRCC tumors (Figure S1A).
