  • 功能：
    Important for the overall degradation of proteins in lysosomes.
  • 基因功能参考文献：
    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
