    SUBCELLULAR LOCALIZATION extracellular
    basic FUNCTION
  • essential for normal development of the catecholamine and renin-angiotensin pathways and the synthesis of different collagens
  • involved in nervous system development
  • mediator for intercellular transfer of drug resistance
  • promoting the migration of inflammatory leukocytes
  • playing important roles in the formation of intraperitoneal adhesions, at least partly by promoting the migration of macrophages and neutrophils to the omentum
  • implicated in the tumorigenesis of benign and plexiform neurofibromas, and therefore arising malignant peripheral nerve sheath tumors (MPNSTs)
  • CELLULAR PROCESS nucleotide, transcription
