产品介绍 : MELK a new member of the Snf1/AMPK family of kinases, encodes a protein with a kinase catalytic domain and a leucine zipper motif consisting of a periodic repetition of leucine residues at every seventh residue located within the N-terminal catalytic domain. This motif has been observed in myriad DNA-binding proteins and is presumed to be involved in protein-DNA interactions, and potentially protein-protein interactions. Research predicts that the gene product of MELK plays a role in the signal transduction events in the egg and early embryo. Mouse and human MELK proteins share 95% sequence identity in the kinase domain and northern blot analysis in mouse indicates that MELK expression is restricted to spermatogonia in the testis and to oocytes in the ovary.
Function:
Phosphorylates ZNF622 and may contribute to its redirection to the nucleus. May be involved in the inhibition of spliceosome assembly during mitosis.
Subunit:
Monomer. Interacts with ZNF622 and PPP1R8.
Subcellular Location:
Cytoplasm.
Tissue Specificity:
Expressed in placenta, kidney, thymus, testis, ovary and intestine.
Post-translational modifications:
Autophosphorylated. Thr-478 phosphorylation during mitosis promotes interaction with PPP1R8.
DISEASE:
Note=Defects in MELK are associated with some cancers, such as brain or breast cancers. Expression is dramatically increased in aggressive undifferentiated tumors, correlating with poor patient outcome in breast and brain cancers, suggesting a role in tumor-initiating cells and proliferation via its function in cell proliferation regulation.
Similarity:
Belongs to the protein kinase superfamily.
CAMK Ser/Thr protein kinase family. SNF1 subfamily.
Contains 1 KA1 (kinase-associated) domain.
Contains 1 protein kinase domain.
SWISS:
Q14680

文献和实验转导通路调控细胞生长和分化，JNK和p38 MAPK信号转导通路在炎症与细胞凋亡等应激反应中发挥重要作用。使用这一芯片试剂盒检测RNA实验标本，操作者通过杂交反应技术，即可研究实验系统中与MAPK信号通路相关基因表达水平改变。 MAPK属于一种Ser/Thr蛋白激酶，可在多种不同的信号转导途径中充当一种共同的信号转导成份，且在细胞周期 调控中发挥重要的作用。目前MAPK家族中至少有4个成员已被纯化和深入 研究。如p42mapk，p44erk1，p54MAPK及p44mpk。
很多人做信号通路研究时，费了九牛二虎之力，好不容易找到了下游底物。满心欢喜地以为守得云开月明，岂料怎么也找不到可用的泛磷酸化抗体，下游的实验也难以开展。制备一个特异性的抗体呗，耗时耗力不说，好不好用还不知道。有没有什么其他办法呢？其实市面上可供选择的泛磷酸化抗体很多很多，关键是你能不能找到其中适合你的那一款。大部分蛋白激酶都有偏好的底物蛋白序列，例如 AMPK 偏好的序列是 LXRXXS*/T*，AKT 偏好的序列是 RXRXXS*/T*。检测以上两种蛋白激酶的底物磷酸化都有可用的商品化抗体

2 从线粒体外膜脱落，进入细胞浆中。在细胞浆中，HK2 结合 NF-κB 的抑制因子 IκBα。 重要的是，HK2 发挥了不依赖于其经典代谢功能的新功能，即作为一个蛋白激酶磷酸化 IκBα 的 Thr 291 位点。该磷酸化促进了蛋白酶 μ-calpain 与 IκBα 的结合并进一步降解 IκBα，进而使转录因子 NF-κB 入核，最终促进了 PD-L1 的表达并导致了肿瘤的免疫逃逸。作者还发现，使用己糖激酶的抑制剂与 PD-1 抗体联用治疗小鼠胶质瘤，可以显著提升 PD-1 抗体的治疗
