Abstract
Neuregulin(NRG)is a signaling transduction protein among cells,the functional receptors of which are ErbB tyrosine kinases receptors,members of the EGF receptor superfamily,which includes:ErbB1,ErbB2/Her2/neu,ErbB3/HER3,and ErbB4/HER4.NRG via inducing ErbB dimerization activates the ErbB kinase domain,resulting in C-ferminal end auto-and trans-phosphorylation of the intracellular domains,playing its biological role through invoking downstream signaling pathway transduction.
