Activity

  • Function:  The insulin-like growth factors possess growth-promoting activity. Major fetal growth hormone in mammals. Plays a key role in regulating fetoplacental development. IGF-II is influenced by placental lactogen. Also involved in tissue differentiation. Positi
  • Mechanism:  The IGF2 locus is imprinted. Paternal inherited gene is expressed, while the maternal inherited gene is imprinted, hence silenced.
