Irradiation (IR) induces phosphorylation of BRCA1-associated protein 1 (BAP1). (a) Western blot analysis with anti-pS592-BAP1 antibody revealed that endogenous WT BAP1 was phosphorylated after IR at 7.5 Gy. (b) BAP1 phosphorylation levels increased in proportion to IR doses. *Non-specific bands. (c) Immunofluorescence analysis showed dominant nuclear localization of phosphorylated-BAP1 protein at 1 h post-IR (7.5 Gy). (d) Western blot analysis of nuclear/cytoplasmic fractionation tested the localization of exogenously transduced BAP1 and its phosphorylated form in malignant mesothelioma cells with BAP1 deletion. HD, homozygous deletion.
