    basic FUNCTION
  • regulator of cell proliferation
  • plays a crucial role in mitogenic regulation of human brain tumor stem cells
  • differentiation of specific cells and mitogenic factor for cells of ectodermal and mesodermal origin
  • antagonistically involved in both PTK2 phosphorylation and dephosphorylation with different mechanisms in a cell
  • EGF and FGF2, may play an important role in the fate decision of neural crest progenitors and in the development of the peripheral nervous system
  • activates ERBB1/ERBB1 or ERBB1/ERBB2 dimers
  • caspase-8 is necessary for the efficient activation of downstream events associated with epidermal growth factor (EGF) signaling
  • EGF with nucleotides carry the potential to act synergistically in the control of cell proliferation and cell survival in adult neurogenesis
  • EGF and TGFA retain some level of functional redundancy, possibly resulting from their divergence from a common ancestral gene
  • inhibits SLC9A8 gene expression through reducing its basal transcription, suggesting an important role of EGF in regulating SLC9A8 expression during intestinal maturation)
  • involved in nervous system development
  • EGF-induced cell migration is mediated by the lipase domain of PLCG1 and the subsequent IP(3) generation and intracellular calcium mobilization
  • promotes breast cancer tumour growth and survival, rapidly induces SERPINE1 expression in the breast adenocarcinoma cell line
  • crucial regulatory mechanism for EGF in GFER transcription within the promoter proximal region
  • IGF1 and epidermal growth factor (EGF) play important roles in the regulation of cell metabolism in response to different internal as well as external stimuli
  • may play a role in the function of the endocrine pancreas and in the pathogenesis of the diabetes mellitus
  • CELLULAR PROCESS cell life, differentiation

    small molecule metal binding,
  • Ca2+
  • protein
  • stimulating histone H3 phosphorylation,RSK2 dependent
  • rapidly depolymerizing actin and inducing formation of membrane ruffles
  • activating phospholipase D1b
  • cooperation between the EGF/EGFR and PTGES leads to a significant tumorigenic gain in epithelial cells
  • EGF controls the levels of CLDN2 and CLDN4 proteins and mRNAs through SRC and STAT3 activity
  • cell & other
  • protecting microtubules assembly of F-actin cytoskeleton and intestinal barrier integrity against oxidant injury, PRKZ dependent
