| 产品介绍 |
Kallikrein 9, also known as Kallikrein-Like 3 (KLK-L3), is a chymotrypsin-like serine proteinase. Kallikrein 9 was discovered as the locus for kallikreins on chromosome 19 was more fully mapped and found by similarity to the other tissue kallikreins. Kallikrein 9 has been found in the ovary, thymus, testis, prostate, skin, breast and neuronal tissues and is made by many cell lines in culture. Kallikrein 9 levels in breast cancer and uterine cancer patients have been reported to drop as the disease progresses, thus hK9 might be considered a favorable prognostic marker. Different splice variants of hK9 have been reported, although it is not yet known if they produce functional proteins. The full length Kallikrein 9 encodes for a 250 amino acid protein, with a predicted mass of 27.5 kDa and a pI of 7.53. The 234 amino acid form predicts a protein of 26 kDa with a pI of 9.76 and this quite basic pI might give the shorter form a very different function or localization. The shorter sequence also diverges before the catalytic serine residue, making it unlikely to be proteolytically active. Pre-pro-kallikrein 9 has the 17 amino acid signal sequence is removed before secretion, and the Pro-kallikrein 9 is activated to Kallikrein 9 by removal of the 5 amino acid propeptide domain. SWISS: Q9UKQ9 Gene ID: 284366 KLK9目前认为是卵巢癌 宫颈癌 子宫内膜癌等其他肿瘤,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。 |
