特異性
Detects a band at 55kDa in mouse A20 cells that we believe corresponds to Plk1 (predicted molecular weight 68kDa). Also gives positive staining in immunohistochemistry in human colon carcinoma as expected. However, we have been unable to conclusively demonstrate the specificity of the antibody for phospho T210 Plk1.
Anti-Polo-like Kinase pT210 Antibody is directed against human phosphorylated Plk1 protein. This antibody is specific for phosphorylated human Plk-1 protein at the pT210 residue. BLAST analysis indicates 100 % homology of the immunizing sequence with Plk-1 homologues from human, chimpanzee, pig, chicken, mouse, rat, Xenopus, dog, mosquito, zebra fish, starfish, sea urchin and fruit fly. Cross reactivity with Plk-1 protein homologues from C.elgans and honeybee may also occur as sequence homology varies by one amino acid residue in this sequence. Reactivity with Plk-1 protein from other sources is not known. Minimal reactivity is expected with the non-phosphorylated form of the protein.

機能
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. -
組織特異性
Placenta and colon. -
配列類似性
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. CDC5/Polo subfamily.
Contains 2 POLO box domains.
Contains 1 protein kinase domain. -
発生段階
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. -
翻訳後修飾
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. -
細胞内局在
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. - Information by UniProt

Western blot - Anti-PLK1 (phospho T210) antibody (ab12157)Anti-PLK1 (phospho T210) antibody (ab12157) at 1/500 dilution + Mouse A20 cell lysate
Predicted band size: 68 kDa
Observed band size: 55 kDa why is the actual band size different from the predicted?
Additional bands at: 23 kDa, 40 kDa, 42 kDa. We are unsure as to the identity of these extra bands.
We believe the 55kDa band represents Plk1. However, we cannot be sure that the antibody is detecting phospho T210 Plk1 specifically. -
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-PLK1 (phospho T210) antibody (ab12157)ab12157 was used at a 1:200 dilution to detect Plk1 by immunohistochemistry in human colon carcinoma tumor tissue. Tissue was formalin-fixed and paraffin embedded. Detection with AEC (pink), nuclear counterstaining with Haematoxylin (blue). -
