To further delineate the downstream regulatory mechanism underlying the oncogenic roles of LINK-A, we performed mass spectrometry (MS) analyses to identify proteins precipitated with LINK-A in KYSE450 and YES2 cells. In total, 43 and 14 LINK-A-interacting proteins were identified in KYSE450 and YES2 cells, respectively, and 7 of these interacting proteins were identified in both cell lines
