产品介绍

    KLK7目前认为是卵巢癌 宫颈癌 前列腺癌等其他肿瘤,很有意义的标志物。激肽释放酶KLK是激肽系统的主要限速酶，它是一组存在于多数组织和体液中的丝氨酸蛋白酶，是一种肽链内切酶。KLK又称血管舒缓素，包括15个家族成员。在不同的组织中广泛表达,具有蛋白水解酶的活性。它特异性的在碳末端切割底物肽，可裂解激肽原释放具有活性的激肽，由激肽发挥对心血管系统及肾脏功能的调节作用。
    组织KLK是一个大的基因家族，主要分布在肺、肾、血管、脑、肾上腺组织，为一种中等大小的糖蛋白。
    The human tissue Kallikrein gene family encodes 15 serine proteases. All Kallikreins share structural similarities including cysteine residues, a catalytic triad of His, Asp, and Ser residues, typically five coding exons and varied intron phases. Kallikreins are predominantly secreted as inactive zymogens prior to activation by cleavage of an N-terminal peptide and all function extracellularly. Kallikreins can be activated autocatalytically, via other Kallikreins, or additional proteases. While structurally similar, Kallikrein family members have distinct functions and have key roles in many physiological and pathological processes. Many human tissue Kallikreins also show promise as cancer biomarkers, which may facilitate earlier detection and characterization of many forms of cancer.
    Kallikrein 7, also known as stratum corneum chymotryptic enzyme (SCCE) and PRSS6, is a chymotrypsin-like serine proteinase. Originally described from human skin as a serine protease involved in shedding of skin cells and remodeling if the skin, SCCE was later identified as Kallikrein 7. Kallikrein 7 is found at the highest levels in the skin, often complexed with the endogenous serpins SLPI or elafin and kallikrein 7 can be found complexed to a number of different proteinase inhibitors. In addition to skin, Kallikrein 7 has been found in the kidney, esophagus, neuronal tissues, amniotic fluid, saliva, breast milk, urine, synovial fluid, seminal plasma and serum. Kallikrein 7 has been reported to be decreased in the CSF of Alzheimer's patients and message levels of KLK7 were decreased in adenocarcinoma. In skin, overexpression of hK7 has been shown to cause a form of dermatitis and in psoriasis hK7 is expressed in higher levels than controls. The skin adhesive proteins corneodesmosin and desmocollin 1 have been reported to be substrates of Kallikrein 7, as is interleukin 1 and the insulin B-chain.
