Angiotensin I Converting Enzyme (ACE-2), also called ACEH (ACE homologue), is a dimeric, zinc-dependent metalloprotease of the ACE family that also includes somatic and germinal ACE. ACE-2 mRNA is found at high levels in heart, testis, and kidney and at lower levels in a wide variety of tissues. ACE-2 is the SARS-CoV and SARS-CoV2 Spike protein receptor in vivo, functions catalytically as a carboxypeptidase to cleave several substrates including angiotensins I and II, and acts as a partner for B0AT1-family amino acid transporters. Through these functions, ACE-2 has been shown to be involved in several diseases including SARS, COVID19, acute lung injury, heart disease, liver and lung fibrosis, inflammatory lung disease, and cardiopulmonary disease . Full length ACE-2 protein includes an extracellular region composed of a single N-terminal peptidase domain and C-terminal collectrin-like domain (CLD), a transmembrane domain, and a short cytoplasmic tail. The N-terminal peptidase region is required for binding to SARS-CoV and SARS-CoV2 spike proteins, while the CLD contains a region that promotes dimerization and association with amino acid transporters.LAG-1與MIP-1β(ACT II同種型)相同,Lag-1趨化吸引力單核細(xì)胞,并表現(xiàn)出活性作為HIV抑制因子。Recombinant Human CDH17/Cadherin 17 Domain 7 Protein,hFc Tag

產(chǎn)品描述纖維蛋白原(Fibrinogen,F(xiàn)g),即凝血因子I,分子量約340kDa,由α、β、γ三對不同多肽鏈組成,多肽鏈間以二硫鍵相連。α鏈分子量63.5kDa,β鏈分子量56kDa,γ鏈分子量47kDa,纖維蛋白原約含4%碳水化合物。纖維蛋白原參與凝血的原理:在凝血酶作用下,α鏈與β鏈分別釋放出A肽與B肽,生成纖維蛋白單體。在此過程中,由于釋放了酸性多肽,負(fù)電性降低,單體易于聚合成纖維蛋白多聚體,但此時(shí)單體之間借氫鍵與疏水鍵相連,尚可溶于稀酸和尿素溶液中。進(jìn)一步在Ca2+與活化的ⅩⅢ因子作用下,單體之間以共價(jià)鍵相連,則變成穩(wěn)定的不溶性纖維蛋白凝塊,完成凝血過程。來源于不同物種(如來源于牛、貓、狗、豚鼠、人、綿羊、小鼠和大鼠等)的纖維蛋白原具有相似的結(jié)構(gòu)和性質(zhì)。因此,一般來源于一種哺乳動物的纖維蛋白原可與其他來源的凝血酶交叉反應(yīng),相反地來自一種哺乳動物蛋白的凝血酶液也可注入多種動物,發(fā)生凝血反應(yīng)。
