basic FUNCTION
  • may be involved in the neonatal adaptation of circulatory system, osteoporosis, as well as initiation of skin immune responses
  • involved in the regulation of collagen type-1, MMP1 & MMP3 in human tendon fibroblasts
  • transducing Prostaglandin E2 (PGE2) signal
  • mediating IL-1beta metabolism via the p38 MAPK pathway in human tendon fibroblasts
  • may play a major role in the tendon's degenerative changes
  • directly involved in regulation of proliferation and invasion of inflammatory breast cancer cells
  • involved in mechanisms for prostaglandin E(1) actions on the cochlea
