    basic FUNCTION
  • may play a role in the regulation of renal and intestinal calcium and phosphate transport, cell metabolism, or cellular calcium/phosphate homeostasis
  • promotes epithelial-mesenchymal transition and invasiveness in hypoxic human ovarian cancer cells
  • functional homodimeric glycoprotein, and thecal cell-derived STC2 could play a paracrine role during follicular development
  • dual role for STC2 in neuroblastoma, reduces proliferation of tumor cells in vitro, but increases the invasive potential and induces bleeding, and thereby may facilitate early metastasis
    • and is a positive regulator in tumor progression at hypoxia
  • involvement of STC2 in responding to pancreatic acinar cell injury
  • prosurvival component of the unfolded protein response
  • cell-intrinsic role for STC2 in the regulation of store-operated Ca(2+) entry (SOCE), and modulation of SOCE through STC2 expression is one of the prosurvival measures of the unfolded protein response
  • functions likely as a stress protein
  • is a novel receptor target gene previously reported to have a cytoprotective role in endoplasmic reticulum stress
  • STC1, STC2 are known to be involved in tumor progression and metastasis
  • STC1 and STC2 play positive roles in angiogenic sprouting
  • is a novel proteinase inhibitor and a previously unrecognized extracellular component of the IGF system
  • STC2 can be used to enhance cell survival and maintain long-term stemness in therapeutic use of stem cells
  • CPNE1 and STC2, were confirmed to be modifiers of in vitro myogenesis
    • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling hormonal
    a component
  • HMOX1-STC2 complex may represent a eukaryotic ‘stressosome’ in conditions where heme is liberated
    • INTERACTION
    DNA
    RNA
    small molecule metal binding,
    metal ions
    protein
  • caseine kinase 2
  • HMOX1 is a binding partner of STC2
  • STC2 binds hemin via a consensus heme regulatory motif
  • potently inhibits the proteolytic activity of the growth-promoting metalloproteinase, pregnancy-associated plasma protein-A (PAPPA)
  • presence of native complexes between PAPPA and STC1, STC2 in the human ovary, indicating STC-mediated PAPPA proteolytic inhibition
    • cell & other
    REGULATION
    activated by EIF2AK3, (PKR)-like Endoplasmic Reticulum Kinase (PERK) signalling, under conditions of ER stress in vitro
