  • 应用说明Is unsuitable for ICC/IF.
  • 靶标

    • 功能Serine/threonine-protein kinase that performs several important functions throughout M phase of the cell cycle, including the regulation of centrosome maturation and spindle assembly, the removal of cohesins from chromosome arms, the inactivation of APC/C inhibitors, and the regulation of mitotic exit and cytokinesis. Required for recovery after DNA damage checkpoint and entry into mitosis. Required for kinetochore localization of BUB1B. Phosphorylates SGOL1. Required for spindle pole localization of isoform 3 of SGOL1 and plays a role in regulating its centriole cohesion function. Phosphorylates BORA, and thereby promotes the degradation of BORA. Contributes to the regulation of AURKA function. Regulates TP53 stability through phosphorylation of TOPORS.
    • 组织特异性Placenta and colon.
    • 序列相似性Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. CDC5/Polo subfamily.
      Contains 2 POLO box domains.
      Contains 1 protein kinase domain.
    • 发展阶段Accumulates to a maximum during the G2 and M phases, declines to a nearly undetectable level following mitosis and throughout G1 phase, and then begins to accumulate again during S phase.
    • 翻译后修饰Catalytic activity is enhanced by phosphorylation of Thr-210. Phosphorylation at Thr-210 is first detected on centrosomes in the G2 phase of the cell cycle, peaks in prometaphase and gradually disappears from centrosomes during anaphase.
      Autophosphorylation and phosphorylation of Ser-137 may not be significant for the activation of PLK1 during mitosis, but may enhance catalytic activity during recovery after DNA damage checkpoint.
      Ubiquitinated by the anaphase promoting complex/cyclosome (APC/C) in anaphase and following DNA damage, leading to its degradation by the proteasome. Ubiquitination is mediated via its interaction with FZR1/CDH1. Ubiquitination and subsequent degradation prevents entry into mitosis and is essential to maintain an efficient G2 DNA damage checkpoint.
    • 细胞定位Nucleus. Chromosome > centromere > kinetochore. Cytoplasm > cytoskeleton > centrosome. During early stages of mitosis, the phosphorylated form is detected on centrosomes and kinetochores. Localizes to the outer kinetochore. Presence of SGOL1 and interaction with the phosphorylated form of BUB1 is required for the kinetochore localization.

      Lane 1: Mitotic CSF Xenopus egg extract
      Lane 2: Interphase Xenopus egg extract
      Lane 3: HeLa cell extract

      Note that the phosphorylated form of Plx from the Xenopus mitotic extract migrates slower than the unphosphorylated form present in the interphase extract.

    Many thanks for the image, it is very useful. I would recommend incubating the membrane in the antibody overnight at 4C in TBST and also trying more concentrated antibody (such as 2-5ug/ml), if you still experience problems with those conditions ple...

    I'm sorry to hear you are having no signal with ab12211 in WB. Could you please tell me the dilution and incubation time you have tested and send me an image of the blot? I look forward to hearing from you, Thank you in advance,
