Description
Product Usage Information
Western Blotting: 1:1000
Storage
Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at -20°C. Do not aliquot the antibody.
Protocol
Available protocols: Western Blotting
Specificity / Sensitivity
PBK/TOPK Antibody detects endogenous levels of total PBK/TOPK protein.
Species Reactivity: Human, Mouse, Rat
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to amino acids at the carboxy-terminus of human PBK/TOPK. Antibodies are purified by protein A and peptide affinity chromatography.
Background
PBK/TOPK is a serine/threonine kinase that is phosphorylated and active during mitosis (1). PBK/TOPK is composed of kinase subdomains and a carboxy-terminal PDZ-binding domain, which is thought to interact with the human homologue of the Drosophila Discs large (hDlg) tumor suppressor protein (1). Increased PBK/TOPK expression has been observed in highly proliferative malignant cell lines, and PBK/TOPK expression is strongly downregulated during terminal differentiation of HL-60 leukemic cells (2,3). PMA-induced kinase activity toward PBK/TOPK has been observed (4), and cdc2/cyclin B has been shown to phosphorylate PBK/TOPK , presumably at Thr9 (5). Potential substrates of PBK/TOPK include p38 MAPK and c-Myc (3,4).
