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

ERBB3,又稱HH3(人表皮生長因子受體3),是一種I型膜糖蛋白,是酪氨酸激酶受體ERBC家族的成員。ERBP家族成員作為表皮生長因子(LU)家族的生長因子的受體。在ERBP家庭成員中,因為它含有一個缺陷的激酶域。ERBB3在角化細(xì)胞、黑色素細(xì)胞、骨骼肌細(xì)胞、成肌細(xì)胞和雪旺細(xì)胞中都有表達(dá)。單體ERbb3是一種低親和性的受體。ERBB3與ERBB2的異聚反應(yīng)形成高親和性受體復(fù)合物。與此相反,ERBB3同向聚合或異向聚合形成了一個低親和性的結(jié)合物。因為ERBB3含有一個有缺陷的激酶域,ERBB2的激酶域負(fù)責(zé)通過異二重瓣受體啟動酪氨酸磷酸化信號。研究發(fā)現(xiàn),ERBB3細(xì)胞質(zhì)區(qū)內(nèi)的三個離散氨基酸信號對ERBB2的轉(zhuǎn)導(dǎo)至關(guān)重要。ERBB3的細(xì)胞質(zhì)域也包含6個一致的結(jié)合主題,用于調(diào)節(jié)P85磷酸酶3激酶(PI3K)的HS2領(lǐng)域,以及一個豐富的一致的結(jié)合主題。ERBB3的細(xì)胞質(zhì)域也包含6個一致的結(jié)合主題,用于調(diào)節(jié)P85磷酸酶3激酶(PI3K)的HS2領(lǐng)域,以及一個豐富的一致的結(jié)合主題。ERBB3的細(xì)胞質(zhì)域也包含6個一致的結(jié)合主題,用于調(diào)節(jié)P85磷酸酶3激酶(PI3K)的HS2領(lǐng)域,以及一個豐富的一致的結(jié)合主題。表達(dá)區(qū)間及表達(dá)系統(tǒng)重組的人HR3/ERBB3蛋白表達(dá)自于C-端的HK293細(xì)胞和AVI標(biāo)記。里面有血清20-Thr643。分子量大約71.6Recombinant Human Apolipoprotein A-I ProteinFGF-18將破骨細(xì)胞和成骨細(xì)胞募集到生長板中,促進(jìn)破骨細(xì)胞的形成和功能,促進(jìn)骨骼血管形成。

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)。
