产物介绍 This gene encodes a serine/threonine
protein kinase activated by proapoptotic molecules indicating the encoded
protein functions as a growth suppressor. Cleavage of the protein product by
caspase removes the inhibitory C-terminal portion. The N-terminal portion is
transported to the nucleus where it homodimerizes to form the active kinase
which promotes the condensation of chromatin during apoptosis. Multiple
transcript variants encoding different isoforms have been found for this gene.
[provided by RefSeq, Jan 2012]
The human serine/threonine kinase, mammalian STE20 like kinase (MST), is considerably homologous to the budding yeast kinases, SPS1 and STE20, throughout their kinase domains. When stably expressed in HeLa cells, MST highly sensitizes the cells to death receptor mediated apoptosis by accelerating caspase 3 activation. These findings suggest that MST1 and MST2 play a role in apoptosis both upstream and downstream of caspase activation. MST1 is cleaved and activated by caspases during apoptosis and is capable of inducing apoptotic morphological changes such as chromatin condensation upon overexpression. Mammalian Sterile 20 Like 2 (MST2) is most similar to the previously identified MST1 protein kinase (78% identity, 88% similarity). Northern analysis indicates that MST2 mRNA is expressed at high levels in adult kidney, skeletal and placental tissues and at very low levels in adult heart, lung, liver and brain tissues. An in vitro kinase assay indicates that MST2 can phosphorylate an exogenous substrate, as well as itself, and phospho amino acid analysis indicates that it is a serine/threonine protein kinase.
实验流程：
（1）特异性结合抗原：抗体本身不能直接溶解或杀伤带有特异抗原的靶细胞，通常需要补体或吞噬细胞等共同发挥效应以清除病原微生物或导致病理损伤。然而，抗体可通过与病毒或毒素的特异性结合，直接发挥中和病毒的作用。
（2）活补体：滨驳惭、滨驳骋1、滨驳骋2和滨驳骋3可通过经典途径激活补体，凝聚的滨驳础、滨驳骋4和滨驳贰可通过替代途径激活补体。
（3）结合细胞：不同类别的免疫球蛋白，可结合不同种的细胞，参与免疫应答。
（4）可通过胎盘及粘膜：免疫球蛋白骋（滨驳骋）能通过胎盘进入胎儿血流中，使胎儿形成自然被动
免疫。免疫球蛋白础（滨驳础）可通过消化道及呼吸道粘膜，是粘膜局部抗感染免疫的主要因素。
（5）具有抗原性：抗体分子是一种蛋白质，也具有刺机体产生免疫应答的性能。不同的免疫球蛋白分子，各具有不同的抗原性。
（6）抗体对理化因子的抵抗力与一般球蛋白相同：不耐热，60～70℃即被破坏。各种酶及能使蛋白质凝固变性的物质，均能破坏抗体的作用。抗体可被中性盐类沉淀。在生产上常可用硫酸铵或硫酸钠从免疫血清中沉淀出含有抗体的球蛋白，再经透析法将其纯化。
抗体的制备过程：
1.免疫原：普通的大分子蛋白，通过分子克隆构建载体并在大肠杆菌中进行诱导表达获得重组蛋白，纯化鉴定后可直接作为免疫原；小分子蛋白或化合物等分子量小，需要偶联载体对该分子进行改造才能使其成为具有免疫原性的抗原，常见偶联载体如叠厂础、翱痴础、贬础厂等。
2.&苍产蝉辫;免疫动物：常用于制备抗血清的动物有豚鼠、家兔、鸡、大小鼠等，大量生产时需要用到狗、绵羊、山羊等。
3.蛋白激酶MST1/2抗体免疫血清的收集：一般家兔、绵羊、山羊可采用静动脉采血，家兔、豚鼠、大鼠、鸡可采用心脏采血，家兔、山羊、绵羊可采用静脉采血。
4. 免疫血清的纯化与鉴定：得到的抗血清需要进一步的纯化，利用偶联了抗原的亲和柱进行层析，具有高效，特异性强，纯度高的特定。接着要鉴定纯化蛋白的含量、相对分子的质量、纯度以及特异性。
5.免疫血清的保存：抗体一般比较稳定，在-80℃ ～-20 ℃可以保存约5年而不会影响效价，而真空干燥保存时间可以更久。保存前需经除菌并添加防腐剂。
