Figure 6 ATP11B interacts with PD-L1 in a CMTM6-dependent manner. (A–B) ATP11B interaction with PD-L1 in vivo. Cell lysates from KPC and SW1990 cells were separately subjected to immunoprecipitation and western blotting using the indicated antibodies. (C) Lack of binding of ATP11B to PD-L1 in vitro. FLAG-tagged ATP11B and MYC-tagged PD-L1 purified from 293 T cell lysates and subjected to immunoprecipitation after co-incubation. (D) Positive correlation of ATP11B with CMTM6. Correlation of ATP11B and CMTM6 analyzed according to the pancreatic data sets of The Cancer Genome Atlas. (E–G) Representative images (E–F) and statistical results (G) of CMTM6 and ATP11B immunohistochemical staining in pancreatic cancer tissue microarray. (H) Western blotting of ATP11B, CMTM6, and PD-L1 expression in paired clinical tissue samples. (I–M) Interaction of ATP11B with PD-L1 in pancreatic cancer in a CMTM6-dependent manner. (I−J) cell lysates from KPC and SW1990 cells were separately subjected to immunoprecipitation and western blotting using the indicated antibodies. (K) Western blotting of ATP11B expression in pancreatic cancer cell lines after CMTM6 knockdown. (L–M) Cell lysates from CMTM6-KD KPC (L) and CMTM6-KD SW1990 (M) separately subjected to immunoprecipitation and western blotting using the indicated antibodies. CMTM6, CKLF-like MARVEL transmembrane domain containing 6; PD-L1 programmed cell death ligand 1.
