    basic FUNCTION
  • potentially playing a paracrine/autocrine role
  • promoting the differentiation and mineralization of osteoblast-like cells
  • regulating endochondral bone growth through NPR2
  • important regulator of cartilage homeostasis and endochondral bone growth
  • might be the relevant factor for activation of NPR2 on sensory axons to affect their branching at the DREZ (dorsal root entry zone) (Schmidt 2009)
  • induces a cGMP signaling cascade via its receptor particulate guanylyl cyclase NPR2 which is essential for sensory axon bifurcation at the dorsal root entry zone (DREZ) of the spinal cord (Schmidt 2009)
  • NPPB, NPPA, NPPC activate guanylyl cyclase suggesting a potential role in maintaining lens epithelial cell homeostasis (PMID;
  • stimulates ovarian follicle development
  • NPPC/NPR2 signaling maintains oocyte meiotic arrest in early antral follicles and is suppressed by EGFR-mediated signaling in preovulatory follicles
  • in preovulatory ovarian follicles, the oocyte is maintained in meiotic prophase arrest by natriuretic peptide precursor C (NPPC) and its receptor natriuretic peptide receptor 2 (NPR2)
  • novel role for NPPC/NPR2 in the epididymal epithelium, presumably in context of local water balance
  • play critical roles in cartilage homeostasis and endochondral bone formation
  • age-related reduction in the serum NPPC concentration was highly correlated with decreased oocyte quality

    protein
  • regulating BGN during a specific time period
  • interacting with NPR2 (system important in endochondral ossification, reversing the FGFR3-mediated inhibition of the endochondral ossification)
  • induces bifurcation of ingrowing sensory axons via its receptor NPR2 (Schmidt 2009)
  • signaling by NPPC through its receptor, natriuretic peptide receptor 2 (NPR2), was found to be essential for meiotic arrest at the late antral stage
  • OSTN enhances the abundance of C-type natriuretic peptide (NPPC), thereby promoting cardiomyocyte contractility through protein kinase A and inhibiting fibroblast activation through protein kinase G signaling
