AIMP2 | Â | NCI-H157, A549 and NCI-H460 | Functioned as a proapoptotic factor in response to DNA damage | Interacted with tumor suppressor p53 | |

AIMP2-DX2 | Lung cancer | A549, NCI-H460, H322 and H157 | Increased susceptibility to carcinogen-induced lung tumorigenesis | AIMP2-DX2 impaired the pro-apoptotic activity of AIMP2 through binding to p53 | |
|  | Ovarian cancer | A2780, SKOV3 and HeyA8 | Contributed to the chemoresistance of ovarian cancer | Reduced the pro-apoptotic activity of TNF-α by competitively inhibiting the binding of AIMP2 to TRAF2 | |
