Source / Purification

The GST-Kinase fusion protein was produced using a baculovirus expression system with a construct expressing a fragment of human Aurora C (Met12-Ser275) (GenBank Accession No. NM_003160.1) with an amino-terminal GST tag. The protein was purified by one-step affinity chromatography using glutathione-agarose.

Product Description

The kit provides a means of performing kinase activity assays with recombinant human Aurora C kinase. It includes active Aurora C kinase (supplied as a GST fusion protein), a biotinylated peptide substrate and a phospho-serine antibody for detection of the phosphorylated form of the substrate peptide.
Molecular Formula Peptide substrate, Biotin- PLK (Ser137): 1,945 Daltons. GST-Aurora C Kinase: 74 kDa.

Background

Aurora kinases belong to a highly conserved family of mitotic serine/threonine kinases with three members identified among mammals: Aurora A, B, and C (1,2). Studies on the temporal expression pattern and subcellular localization of Aurora kinases in mitotic cells suggest an association with mitotic structure. Aurora kinase functional influences span from G2 phase to cytokinesis and may be involved in key cell cycle events such as centrosome duplication, chromosome bi-orientation and segregation, cleavage furrow positioning, and ingression (3). Aurora A is detected at the centrosomes, along mitotic spindle microtubules, and in the cytoplasm of mitotically proliferating cells. Aurora A protein levels are low during G1 and S phases and peak during the G2/M phase of the cell cycle. Phosphorylation of Aurora A at Thr288 in its catalytic domain increases kinase activity. Aurora A is involved in centrosome separation, maturation, and spindle assembly and stability. Expression of Aurora B protein also peaks during the G2/M phase of the cell cycle; Aurora B kinase activity peaks at the transition from metaphase to the end of mitosis. Aurora B associates with chromosomes during prophase prior to relocalizing to the spindle at anaphase. Aurora B regulates chromosome segregation through the control of microtubule-kinetochore attachment and cytokinesis. Expression of both Aurora A and Aurora B during the G2/M phase transition is tightly coordinated with histone H3 phosphorylation (4,5); research investigators have observed overexpression of these kinases in a variety of human cancers (2,4). Aurora C localizes to the centrosome from anaphase to cytokinesis and both mRNA and protein levels peak during G2/M phase. Although typical Aurora C expression is limited to the testis, research studies report overexpression of Aurora C is detected in various cancer cell lines (6).
