EEF1A1 and familial pancreatic carcinoma: Having located the cysteine234 residue of eEF1A1 as the most probable binding site of 33 according to LC-MS/MS analysis, they engineered three types of pancreatic cancer cells with (1) eEF1A1 knockdown (KD), (2) eEF1A1 recovered from KD (RE-KD), and (3) C234-mutant eEF1A1 constructed from KD (RE-C234S).
