ERBB2 and cancer: The types of cellular proteins inducing autoantibody responses are quite varied and include oncogene products such as HER-2/neu [26], cellular proteins which shield mRNAs from natural physiological degradation such as p62/IMP2 [27] and CRD-BP [28], onconeural antigens in the paraneoplastic disorder syndrome [29], differentiation-antigens such as tyrosinase and cancer/tetis antigens [30].
