    basic FUNCTION
  • calcium dependent phospholipid binding protein, modulating antiinflammatory response (phospholipase A2 inhibitory activity)
  • involved in the regulation of early delayed glucocorticoid feadback action in the hypothalamo-hypophysial system
  • role of endogenous ANXA1 in the protective and reparative properties of the intestinal mucosal epithelium
  • mediating the glucocorticoid inhibition of cyclic adenosine 3', 5'-monophosphate-stimulated prolactin secretion
  • promoting membrane fusion
  • mediator of the anti-inflammatory actions of endogenous and exogenous glucocorticoids (GC)
  • regulating the MAPK/ERK pathway
  • potent inhibitor of hormone exocytosis in the neuroendocrine system, acting in a paracrine/juxtacrine manner
  • fundamental for brain homeostasis
  • Ca(2+)-dependent membrane binding protein, which has been implicated in membrane trafficking and reorganization
  • important component of phagocytosis that appears to link actin accumulation to different steps of phagosome formation
  • multifunctional, calcium-dependent phospholipid binding protein involved in a host of processes including inflammation, regulation of neuroendocrine signaling, apoptosis, and membrane trafficking
  • may be required for the constitutive activity of IKBKB and NFKB in highly metatstatic breast cancer
  • required for the recruitment of RIPK1 to the IKK complex, which may be important for the activation of NFKB
  • critical for the constitutive activation of NFkB in breast cancer to promote metastasis
  • CELLULAR PROCESS cell communication

    INTERACTION
    DNA
    RNA
    small molecule metal binding, other,
  • calcium Ca2+ (2 to 4 ions with high affinity)
  • calcium- and phospholipid-binding protein
  • protein
  • formyl peptide receptor (FPR)
  • interacting with TSC22D3 (TSC22D3 is a previously unrecognized mechanism of the anti-inflammatory effects of ANXA1)
  • N-terminal tail of ANXA1 can interact with either membranes or S100A11 protein, and it adopts the conformation of an amphipathic alpha-helix upon these interactions
  • binding of annexin A1 to heparin/heparan sulfate is calcium- but not magnesium-dependent
  • can bind to and interact with IKBKG or NEMO, but not IKBKA or IKBKB
  • ANXA1/FPR2 system has an important role in effecting the resolution of cerebral inflammation in sepsis
  • cell & other
    REGULATION
    induced by 17 beta-estradiol in CCRF-CEM cells (synthesis and secretion)
    inhibited by exogenous glucorticoids in brain
    phosphorylated by protein kinase C and epidermal growth factor receptor/kinase
    cleavage by the proteinase 3
    Other Ubiquitination of annexin A1 may play an important role in mutagenesis, an initial step of cell transformation
