  • Research areas

  • Function

    EGF stimulates the growth of various epidermal and epithelial tissues in vivo and in vitro and of some fibroblasts in cell culture. Magnesiotropic hormone that stimulates magnesium reabsorption in the renal distal convoluted tubule via engagement of EGFR and activation of the magnesium channel TRPM6. Can induce neurite outgrowth in motoneurons of the pond snail Lymnaea stagnalis in vitro (PubMed:10964941).
  • Tissue specificity

    Expressed in kidney, salivary gland, cerebrum and prostate.
  • Involvement in disease

    Hypomagnesemia 4
  • Sequence similarities

    Contains 9 EGF-like domains.
    Contains 9 LDL-receptor class B repeats.
  • Post-translational

    O-glycosylated with core 1-like and core 2-like glycans. It is uncertain if Ser-954 or Thr-955 is O-glycosylated. The modification here shows glycan heterogeneity: HexHexNAc (major) and Hex2HexNAc2 (minor).
