Target Background

Function
(From Uniprot)
Displays several functions associated with host defense: it promotes agglutination, bacterial capsular swelling, phagocytosis and complement fixation through its calcium-dependent binding to phosphorylcholine. Can interact with DNA and histones and may scavenge nuclear material released from damaged circulating cells.
Gene References into Functions
  1. CRP is pathogenic in type-2 diabetes (T2DN). CRP may promote CD32b- NF-kappaB signaling to mediate renal inflammation; whereas, CRP may enhance renal fibrosis in T2DN via CD32b-Smad3-mTOR signaling. PMID: 27221338
  2. FcgammaRIIb and FcgammaRIII are involved in the CRP-induced expression of MMPs and TIMP-1 and the CRP-induced phosphorylation of p38, whereas the FcgammaR-independent pathway may regulate the CRP-induced MMP-11 expression and the CRP-induced ERK1/2 phosphorylation. PMID: 28539825
  3. C-reactive protein may promote acute kidney injury by impairing tubular epithelial cell regeneration via the CD32-Smad3-p27-driven inhibition of the CDK2/cyclin E complex. PMID: 27470679
  4. These results suggested that CRP/oxidized low density lipoprotein/beta 2-Glycoprotein I complexes may induce lipid accumulation and inflammation in macrophages via the p38/MAPK and NFkappaB signaling pathways. PMID: 27512978
  5. these data unexpectedly identify CBS as the major recognition site of mCRP and suggest that this motif may be exploited to tune the proinflammatory actions of mCRP. PMID: 26907682
  6. CRP decreased adiponectin expression and multimerization, while CRP-induced decline in adiponectin might be mediated through the PI3K/Akt pathway. PMID: 26812237
  7. mCRP may be responsible for promoting dementia after ischaemia and mCRP clearance could inform therapeutic avenues to reduce the risk of future dementia. PMID: 26335098
  8. Effects of C-Reactive Protein on the Cardiac Differentiation of Mouse Embryonic Stem Cells PMID: 26328491

  11. the acute phase protein C-reactive protein (CRP), a ligand for Fc receptors on phagocytes, enhances antibody-mediated platelet destruction by phagocytes in vivo PMID: 25548320

  13. Orphan nuclear receptor Errgamma induces C-reactive protein gene expression through induction of ER-bound Bzip transmembrane transcription factor CREBH. PMID: 24466039
  14. The interactions of CRP and the BBB are a two-phase process, with increased paracellular permeability at a high dose that enables its entry into the CNS and serves to induce reactive gliosis and impair CNS function. PMID: 23018453
  15. In mice with photochemically induced thrombosis, acrolein produced at the locus of infarction increased the level of IL-6 and then CRP in plasma. PMID: 23763486
  16. CRP directly inhibits tumoral lymphangiogenesis and lymph node metastasis in mice. PMID: 23859309

  19. C-reactive protein promotes acute renal inflammation and fibrosis in unilateral ureteral obstructive nephropathy in mice. PMID: 21383672
  20. These findings reveal a novel nutrient-dependent interaction between Sirt1 and HNF-1alpha which results in regulation of Crp expression. PMID: 21176092
