| ABSTRACT Human epidermal receptors (HER1/2/3/4) belong to the class of receptor-type tyrosine kinases. After binding a ligand, dimerization, it will ocurr activation of intracellular kinases after two-dimensional and cytoplasmic tail reciprocal transphosphorylation. This transphosphorylation recruits signaling pathways such as Ras/Raf/MEK/Erk1-2, PI3-K/AKT and JAK/STAT, which can affect the cell cycle, cytoskeleton reorganization, apoptosis, metastasis, differentiation, angiogenesis and transcription. HER deregulation is found in epithelial, mesenchymal and nervous neoplasms and is associated with poor prognosis and tumor severity. Since HER are promiscuous proteins when subjected to mutations, resultant modifications confer cellular metabolic superiority... |
