In addition, EF1γ is one of the four newly discovered immunogenic proteins of P. multocida, which is identified through 2-DE MALDI-TOF MS analysis with immune serum (Wang et al., 2021), or EF1γ mRNA overexpression was observed in biopsy specimens of esophageal carcinoma, suggesting its use as a possible indicator of tumor aggressiveness (Mimori et al., 1996). The gene discussed is EEF1G; the disease is neoplasm.
