产品介绍 MST1/STK4 encoded by this gene is a cytoplasmic kinase that is structurally similar to the yeast Ste20p kinase, which acts upstream of the stress-induced mitogen-activated protein kinase cascade. The encoded protein can phosphorylate myelin basic protein and undergoes autophosphorylation. A caspase-cleaved fragment of the encoded protein has been shown to be capable of phosphorylating histone H2B. The particular phosphorylation catalyzed by this protein has been correlated with apoptosis, and it's possible that this protein induces the chromatin condensation observed in this process.
Function :
Stress-activated, pro-apoptotic kinase which, following caspase-cleavage, enters the nucleus and induces chromatin condensation followed by internucleosomal DNA fragmentation. Key component of the Hippo signaling pathway which plays a pivotal role in organ size control and tumor suppression by restricting proliferation and promoting apoptosis. The core of this pathway is composed of a kinase cascade wherein STK3/MST2 and STK4/MST1, in complex with its regulatory protein SAV1, phosphorylates and activates LATS1/2 in complex with its regulatory protein MOB1, which in turn phosphorylates and inactivates YAP1 oncoprotein and WWTR1/TAZ. Phosphorylation of YAP1 by LATS2 inhibits its translocation into the nucleus to regulate cellular genes important for cell proliferation, cell death, and cell migration. STK3/MST2 and STK4/MST1 are required to repress proliferation of mature hepatocytes, to prevent activation of facultative adult liver stem cells (oval cells), and to inhibit tumor formation (By similarity). Phosphorylates 'Ser-14' of histone H2B (H2BS14ph) during apoptosis. Phosphorylates FOXO3 upon oxidative stress, which results in its nuclear translocation and cell death initiation. Phosphorylates MOBKL1A, MOBKL1B and RASSF2. Phosphorylates TNNI3 (cardiac Tn-I) and alters its binding affinity to TNNC1 (cardiac Tn-C) and TNNT2 (cardiac Tn-T). Phosphorylates FOXO1 on 'Ser-212' and regulates its activation and stimulates transcription of PMAIP1 in a FOXO1-dependent manner. Phosphorylates SIRT1 and inhibits SIRT1-mediated p53/TP53 deacetylation, thereby promoting p53/TP53 dependent transcription and apoptosis upon DNA damage. Acts as an inhibitor of PKB/AKT1. Phosphorylates AR on 'Ser-650' and suppresses its activity by intersecting with PKB/AKT1 signaling and antagonizing formation of AR-chromatin complexes.
Subunit :
Homodimer; mediated via the coiled-coil region. Interacts with NORE1, which inhibits autoactivation. Interacts with and stabilizes SAV1. Interacts with RASSF1. Interacts with FOXO3. Interacts with RASSF2 (via SARAH domain). Interacts with AR, PKB/AKT1, TNNI3 and SIRT1.

Cytoplasm. Nucleus. Note=The caspase-cleaved form cycles between the nucleus and cytoplasm.
磷酸化蛋白激酶MST1抗体0.1ml/100μg抗体的多样性:
抗体的异质性。抗体的组成极为复杂,是由成千上万、多种多样的免疫球蛋白(Ig)分子所组成。这些Ig分子在形状、大小、结构以及氨基酸的组成和排列上,既相似,又有差别。由于有差别,它们的电泳活性就有很大的变化。
因为抗体具有与抗原决定簇相对应的结合部位(抗原结合簇),所以抗体与抗原的结合具有特异性。另一方面,抗体本身是一种蛋白质,具有本身的氨基酸组成、排列和立体结构,对异种动物来说,它又是抗原。各类Ig都具有可用血清学方法检出的抗原特异性,它们表现出不同的血清学类型。


磷酸化蛋白激酶MST1抗体0.1ml/100μg实验步骤
① 滴加0.01mol/L,pH7.4的PBS于待检标本片上,10min后弃去,使标本保持一定湿度。
② 滴加适当稀释的荧光标记的抗体溶液,使其完全覆盖标本,置于有盖搪瓷盒内,保温一定时间(参考:30min)。
③ 取出玻片,置玻片架上,先用0.01mol/L,pH7.4的PBS冲洗后,再按顺序过0.01mol/L,pH7.4的PBS三缸浸泡,每缸3-5 min,不时振荡。
④ 取出玻片,用滤纸吸去多余水分,但不使标本干燥,加一滴缓冲甘油,以盖玻片覆盖。
⑤ 立即用荧光显微镜观察。观察标本的特异性荧光强度,一般可用“+”表示:
-)无荧光;(±)极弱的可疑荧光;(+)荧光较弱,但清楚可见;(++)荧光明亮;(+++ --++++)荧光闪亮。待检标本特异性荧光染色强度达“++”以上,而各种对照显示为(±)或(-),即可判定为阳性。
注意事项
1)对荧光标记的抗体的稀释,要保证抗体的蛋白有一定的浓度,一般稀释度不应超过1:20,抗体浓度过低,会导致产生的荧光过弱,影响结果的观察。
2)染色的温度和时间需要根据各种不同的标本及抗原而变化,染色时间可以从10 min到数小时,一般30 min已足够。染色温度多采用室温(25℃左右),高于37℃可加强染色效果,但对不耐热的抗原(如流行性乙型脑炎病毒)可采用0-2℃的低温,延长染色时间。低温染色较37℃30 min效果好的多。
3)为了保证荧光染色的正确性,首次试验时需设置下述对照,以排除某些非特异性荧光染色的干扰。
① 标本自发荧光对照:标本加1-2滴0.01mol/L,pH7.4的PBS。
② 特异性对照(抑制试验):标本加未标记的特异性抗体,再加荧光标记的特异性抗体。
③ 阳性对照:已知的阳性标本加荧光标记的特异性抗体。
如果标本自发荧光对照和特异性对照呈无荧光或弱荧光,阳性对照和待检标本呈强荧光,则为特异性阳性染色。
4)一般标本在高压汞灯下照射超过3min,就有荧光减弱现象,经荧光染色的标本zui好在当天观察,随着时间的延长,荧光强度会
