產(chǎn)品詳情

  • 產(chǎn)品描述：
    大鼠組織蛋白酶K(cath-K)酶聯(lián)免疫試劑盒（CSB-E09439r）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的CTSK含量。CTSK（組織蛋白酶K）是一種在骨重塑過程中起關(guān)鍵作用的酶，主要在破骨細胞中表達。其研究機制涉及降解骨細胞外基質(zhì)，促進骨吸收。CTSK在多種癌癥中表達，可能促進腫瘤細胞增殖、侵襲和遷移。研究CTSK有助于開發(fā)新的治療策略。試劑盒檢測范圍為15.6 pg/mL-1000 pg/mL，適用于大鼠骨代謝研究、骨骼疾病動物模型評估及骨靶向藥物作用機制探索等科研領(lǐng)域，可為骨生物學(xué)、病理機制研究及藥物開發(fā)提供穩(wěn)定可靠的定量分析支持。本品僅用于科研，不用于臨床診斷，產(chǎn)品具體參數(shù)及操作步驟詳見產(chǎn)品說明書。

靶點詳情

  • 功能：
    Thiol protease involved in osteoclastic bone resorption and may participate partially in the disorder of bone remodeling. Displays potent endoprotease activity against fibrinogen at acid pH. May play an important role in extracellular matrix degradation. Involved in the release of thyroid hormone thyroxine (T4) by limited proteolysis of TG/thyroglobulin in the thyroid follicle lumen.
  • 基因功能參考文獻：
    1. the present study identified icariin as a novel therapeutic agent in DXM-induced cartilage injury in rats, and revealed that the activation of miR-206 targeting of cathepsin K may be responsible for the chondroprotective efficacy of icariin PMID: 29207029
    2. cathepsin K, in both its secreted and lysosomal forms, may play a role in the degradation of Sertoli cell residual bodies PMID: 14585819
    3. In conclusion, according to its ability to modulate hypotensive effects of kinins, we propose that cathepsin K is a kininase of biological relevance. PMID: 17181996
    4. Comparison of the S2 site between rat and human cathepsin K sequences indicated that two S2 residues at Ser134 and Val160 in rat are varied to Ala and Leu, respectively, in the human enzyme. PMID: 18664521
    5. The expression pattern of Ctsk in osteoclasts in physiological root resorption in the rat molar was determined. PMID: 18974601
