Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.
To assess the linearity of the assay, samples were spiked with high concentrations of Human CNN1 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Background

(From Uniprot)
Thin filament-associated protein that is implicated in the regulation and modulation of smooth muscle contraction. It is capable of binding to actin, calmodulin and tropomyosin. The interaction of calponin with actin inhibits the actomyosin Mg-ATPase activity.
Gene References into Functions
  1. Studied maternal serum calponin 1 levels in the prediction of delivery within 7 days among pregnancies complicated with threatened preterm labor. Of 73 women included in the study, found the maternal serum calponin 1 level was significantly high in women who delivered within 7 days vs. those who delivered after 7 days. PMID: 28068849
  2. Loss of myoepithelial calponin was specifically associated with gain of the basal marker p63 in adjacent tumor cells. PMID: 26343330
  3. Loss of CNN1 expression is associated with Ovarian Cancer. PMID: 26504022
  4. CNN1 immunohistochemical staining allows ready recognition of intracytoplasmic inclusions, aiding diagnosis of infantile digital fibromatosis. PMID: 24117680
  5. epsilonPKC/ERK/mTOR pathway activation induced by the rescued expression of CNN1 contributed to the improvement of cardiac dysfunction and pathological changes observed in transgenic mice. PMID: 24631115
  6. Calponin knockdown inhibits autophosphorylation. PMID: 24350264
  7. Expression of transforming growth factor-beta (4.3 +/- 1.4 vs 2.6 +/- 2.3, p = 0.01) and calponin (3.7 +/- 0.7 vs 0.6 +/- 1.1, p = 0.05) was lower from infants with vs without a PDA. PMID: 23731614
  8. Calponin-1 expression in the uterine smooth muscle tissue of the body and the lower uterine segment of smooth muscle tissues was significantly different. PMID: 21051832
  9. Inhibition of calponin-1 expression can inhibit uterine smooth muscle cell migration and cause the morphological change and rearrangement of F-actin without affecting its proliferation and apoptosis in vitro. PMID: 20584679
  10. A single intronic CArG element is necessary but insufficient for proper CNN1 expression in vivo. CNN1 overexpression antagonizes arterial injury-induced neointimal formation. PMID: 21817093
  11. D2-40 immunohistochemistry reliably identifies the myoepithelial cells of breast in a variety of lesions in a pattern similar to that of calponin and p63. PMID: 21326813
  12. The point mutation S175T exhibited more resistance to actin rearrangement by cytochalasin D and PDBu than intact CNh1, suppressing cell motility induced by PDBu. PMID: 20530411
  13. expression in tumor vessels is a new and useful means to predict prognosis of hepatocellular carcinoma after hepatic resection PMID: 11920541
  14. results suggest that regulation of h1-calponin is involved in the regulation of differentiation of AR42J cells into insulin-producing cells PMID: 12606518
  15. the calponin homology domain of Vav1 associates with calmodulin and is prerequisite to T cell antigen receptor-induced calcium release in Jurkat T lymphocytes PMID: 17550897
  16. analysis of distinct sites of interaction that form the calponin: gelsolin complex and two calcium switches that control its activity PMID: 17556051
  17. expression of vascular CNN1 in the peripheral region of colon cancer tissues was significantly reduced in association with tumor progression, lymphatic invasion, vascular invasion and recurrence. PMID: 17707120
  18. Calponin and alpha-inhibin are the most useful positive markers for serous microcystic adenoma, and are negative in most entities in the differential diagnosis. PMID: 19391217
