    basic FUNCTION
  • receptor for progesterone
  • with SERBP1 complex functions in events important to early pregnancy including cellular differentiation, modulation of apoptosis and steroidogenesis
  • required for CYP7B1 function and interindividual variation in PGRMC1 function may impact multiple biochemical pathways and drug metabolism
  • mediating the anti-apoptotic action of progesterone in ovarian cells, being important regulator of the cytochrome P450 enzymes, and critical for ovarian function and maintained fertility (Mansouri 2008)
  • function through a protein kinase G-dependent mechanism (Mansouri 2008)
    • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling signal transduction
    a component
  • complexing with SERBP1
  • part of a progesterone binding complex (component of the membrane complex that functions as a receptor for progesterone (P4)) (Mansouri 2008)
    • INTERACTION
    DNA
    RNA
    small molecule other,
  • steroid (like progesterone)
    • protein
  • interacting with SERBP1 (binding partner of PGRMC1)
  • stably binds CYP51A1 (loss of PGRMC1 reduces activity of CYP51A1, blocking cholesterol synthesis and increasing production of toxic sterol intermediates)
    • cell & other
