靶點(diǎn)詳情

  • 功能：
    Metalloproteinase which specifically cleaves IGFBP-4 and IGFBP-5, resulting in release of bound IGF. Cleavage of IGFBP-4 is dramatically enhanced by the presence of IGF, whereas cleavage of IGFBP-5 is slightly inhibited by the presence of IGF.
  • 基因功能參考文獻(xiàn)：

    3. The findings suggest a possible pathophysiological link between the development of Fetal growth restriction and the expression of PAPPA, PAPPA2 and PLAC-1. PMID: 29532882
    4. Data suggest that PGF and PAPPA serve as serum biomarkers for early diagnosis of gestational hypertension.

    18. PAPP-A 1224 SNP has a significant effect on the level and activity of PAPP-A in human follicles, suggesting that the follicular fluid level of bioactive insulin-like growth factor depends on the genotype. PMID: 27793387
    19. This study demonstrated no association between PAPP-A gene rs7020782 polymorphism and Preeclampsia (PE) and intrauterine growth restriction. PMID: 26520690
    20. data indicate that PAPP-A promotes TF expression in human endothelial cells and support the hypothesis that this proteinase, besides being involved in progression of atherosclerosis, does not represent an independent risk factor for adverse cardiovascular events, but it rather might play an "active" role in the pathophysiology of ACS as an effector molecule able to induce a pro-thrombotic phenotype in endothelial cells PMID: 27007282
    21. assessed serum PAPP-A levels in COPD and the associations with disease severity; elevated levels of PAPP-A were observed in patients with COPD PMID: 27090654
    22. STC2 is involved in regulating PAPP-A activity during the development of atherosclerosis PMID: 26983002

    24. measurements of maternal serum PAPP-A concentration in the first trimester predict severe fetal growth restriction more effectively than they predict a birth weight below the 10th percentile among a Chinese population PMID: 25845987
    25. Women with PAPP-A /=90th percentile is protective against small for gestational age, and is associated with an increased risk of large for gestational age for infants born after 32 weeks gestation. PMID: 26773241
    26. Data suggest that incidences of intrauterine growth restriction, pre-eclampsia, preterm birth, and fetal death are significantly greater in pregnant women with low serum levels of PAPP-A in first trimester (9-13 weeks of pregnancy) as compared to control pregnant women; study was conducted in India. PMID: 25773764

    31. PAPP-A determination during the first trimester of pregnancy in women at risk for IUGR makes possible the prophylactic treatment and monitoring of pregnancy. PMID: 27125092
