basic FUNCTION
  • may play a role in fat metabolism
  • PDE3B is involved in the regulation of nutrient-stimulated insulin secretion
  • through hydrolysis of cAMP in pools regulated by Ca(2+), plays a regulatory role in depolarization-induced insulin secretion and the enzyme is associated with the exocytotic machinery in beta-cells
  • PDE3B pathway plays an important role in mediating LEP action in the hypothalamus
  • PDE3B has an important role in the regulation of insulin secretion in pancreatic beta-cells
  • direct role of the PDE3B pathway in mediating LEP signaling in the POMC and NPY neurons-a potential mechanism of leptin signaling in the hypothalamus
  • mediates insulin action in the adipose tissue
  • activation of PDE3B is likely a novel mechanism of insulin signaling in the hypothalamus
  • enzyme that catalyzes hydrolysis of cAMP and cGMP, and is highly expressed in tissues that regulate energy homeostasis
  • PDE3B and/or its downstream signaling partners might be important regulators of energy metabolism in adipose tissue

    protein
  • LEP stimulates phosphodiesterase-3B (PDE3B) activity in the hypothalamus, and PDE3 inhibitor cilostamide reverses anorectic and bodyweight reducing effects of leptin
  • PDE3B links insulin- and cAMP-signaling networks in tissues associated with energy metabolism, including white adipose tissue (WAT)
  • CELF1 is a critical regulator of insulin secretion via activating PDE3B

    REGULATION
    inhibited by cAMP,cGMP
    Phosphorylated by AKT1, but phosphorylation of PDE3B by AKT1 is not required for insulin to suppress adipocyte lipolysis
    Other is activated in response to agents relevant for &
    946;beta-cell function and activation is linked to increased as well as decreased phosphorylation of the enzyme
