  • Function

    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.
  • Tissue specificity

    Placenta and colon.
  • Sequence similarities

    Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. CDC5/Polo subfamily.
    Contains 2 POLO box domains.
    Contains 1 protein kinase domain.
  • Developmental stage

    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.
  • Post-translational

    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.
  • Cellular localization

    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.

Thank you for your inquiry.

While we do not list this as cross reacting with mouse, it is possibnle that it may as the regions are so highly conserved. We generally do not recommend using an antibody created in mouse on mouse tissue because of the high background that may occur.The secondary antibody may recognize endogenous IgG in the sample tissue as well as the primary antibody, which may lead to non-specific staining and high background.

Because we carry over 70,000 products, it isn't feasible for us to keep small sample sizes of our products.

We are happy to reassure our customers that all of our products are covered by our Abpromise, which guarantees that the product will work in the applications and species specified on the datasheet, or we will offer a replacement, credit, or refund within 6 months of purchase.

If the product is to be used in an untested species or application, you may be eligible for our testing discount program if the antibody has not yet been purchased. Please contact our Scientific Support team by replying to this email prior to purchase for more information.

Otherwise, we like to encourage all of our customers to submit an Abreview via the online product datasheet. We always appreciate customer feedback, whether positive or negative, and we make all product information available to researchers. Plus, each Abreview earns Abpoints that can be used for discounts on future purchases or rewards such as Amazon.com gift certificates.

Thank you for contacting Abcam.

The immunogen used for this product has 100% homology with the mouse protein (http://www.uniprot.org/uniprot/Q07832). This product has not yet been tested in this species however. Because this has been raised in mouse, using on mouse tissues may lead to high background. As such we cannot guarantee that it would meet the needs of our customers and do not cover this product under our Abpromise guarantee.

We do offer a number of other antibodies against PLK1 (phospho T 210) which have not been raised in mouse. I would suggest ab12157 as an alternative.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
