General description

Human Plk1 polo box domain (GenBank Accession No. NM_005030), amino acids 367-end with N-terminal GST-tag, MW=53 kDa, expressed in an E. coli expression system.
Polo-like kinase 1 (PLK1) belongs to the PLK family. It comprises polo-box domain (PBD). PBD, in turn, contains polo boxes (PB1 and PB2) with a 6-stranded β sandwich and an α helix as structural elements. The PLK1 gene is mapped to human chromosome 16p12.2.

Application

PLK1 Polo Box Domain active human has been used in the in vitro binding assay with various synthetic peptides coupled to streptavidin beads. It has also been used in binding studies with fluorescein-labeled substrate peptide 5-carboxyfluorescein-GPMQSpTPLNG to test the effect of various inhibitors.

Biochem/physiol Actions

Polo-like kinase 1 (PLK1) is a mitotic kinase that mediates the regulation of various events in mitosis including chromosome segregation, cytokinesis, centrosome maturation, and separation. It activates cell division cycle 25 (CDC25) phosphatase which further regulates mitotic entry. Elevated expression of PLK1 is observed in many tumors.

The polo-like kinase 1 (Plk1) is a critical regulator of cell division that is overexpressed in many types of tumors. Thus, a strategy in the treatment of cancer has been to target the kinase activity (ATPase domain) or substrate-binding domain

Polo-like kinase 1 (PLK1), a member of the Polo-like kinase family, plays an important regulatory role in mitosis and cell cycle progression. PLK1 overexpression is correlated with tumourigenesis and poor prognosis in cancer patients. Therefore, the identification of novel compounds

Centrosomes and cilia are organized by a centriole pair comprising an older mother and a younger daughter. Centriole numbers are tightly regulated, and daughter centrioles (which assemble in S phase) cannot themselves duplicate or organize centrosomes until they have passed

Polo-like kinase (Plk1) is crucial for cell-cycle progression via mitosis. Members of the Polo-like kinase family are characterized by the presence of a C-terminal domain termed the Polo-box domain (PBD) in addition to the N-terminal kinase domain. The PBD of
