Intra-assay Precision (Precision within an assay): CV%<10%        
Three samples of known concentration were tested twenty times on one plate to assess.    
Inter-assay Precision (Precision between assays): CV%<15%        
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 CTSH in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.  
  Sample Serum(n=4)    
1:1 Average % 96

Target Data

Function Important for the overall degradation of proteins in lysosomes.
Gene References into Functions
  1. the up-regulation of MMP genes is mediated through degradation of class IIa histone deacetylases (HDACs) by certain cysteine cathepsins (Cts). PMID: 28157489
  2. Especially, rs3825932 in CTSH has integrative functional evidence supporting the association with type 1 diabetes mellitus. PMID: 26429317
  3. p41 fragment is also shown to reduce the secretion of interleukin-12 (IL-12/p70) during the subsequent maturation of treated dendritic cells. PMID: 26960148
  4. In conclusion, CTSH/rs3825932 and ERBB3/rs2292239 SNPs were associated with reduced risk of progression to proliferative diabetic retinopathy and two-step progression of diabetic retinopathy on the ETDRS scale accordingly. PMID: 26245339
  5. mutation in LRPAP1 is associated with high myopia. Further studies are expected to evaluate the pathogenicity of the variants in CTSH, LEPREL1, ZNF644, SLC39A5, and SCO2. PMID: 25525168
  6. The data provide strong evidence that CTSH is an important regulator of beta-cell function during progression of T1D PMID: 24982147
  7. CtsH-mediated processing of talin might promote cancer cell progression by affecting integrin alphaVbeta3 activation and adhesion strength PMID: 23204516
  8. The processing of procathepsin H is an autocatalytic, multistep process proceeding from an inactive 41kDa pro-form, through a 30kDa intermediate form, to the 28kDa mature form. PMID: 22704610
  9. CTSH overexpression in a subset hepatoma may be thyroid hormone receptor dependent and suggests that this overexpression has an important role in hepatoma progression. PMID: 21217776
  10. These data indicate that cathepsins B, L and S may act as cell-death mediators in in monocytic cells infected with ICP4 and Us3 deletion mutant herpes simplex virus type 1. PMID: 20881085
  11. involvement in processing of hydrophobic surfactant-associated protein C in type II pneumocytes PMID: 12034564
  12. Cathepsin H could contribute to the transformation of LDL to an atherogenic moiety; the process might involve a self-sustaining amplifying circle. PMID: 12615673
  13. kinetic data on substrates hydrolysis and enzyme inhibition show the role of the mini-chain as a framework for transition state stabilization of free alpha-amino groups of substrates and as a structural barrier for endopeptidase-like substrate cleavage. PMID: 14515996
  14. AKR1B1 and CTSH may be good markers for prediction of sensitivity to certain drugs PMID: 14662023
  15. cathepsin H is involved in maturation of the biologically active surfactant associated protein B PMID: 14766755
  16. cathepsin H has a role in progression of colorectal cancer that is distinct from that of cathepsins B and L PMID: 15646835
  17. A general defect in napsin A or cathepsin H expression or activity was not the specific cause for abnormal surfactant accumulation in juvenile pulmonary alveolar proteinosis PMID: 18216060
  18. In contrast to cathepsin S, cathepsin H values did not correlate with markers of inflammation, indicating a specific role for cathepsin H in the pleural host response. PMID: 19404922
