    Protocol

    Specificity / Sensitivity

    PBK/TOPK (F2X2Z) Rabbit mAb recognizes endogenous levels of total PBK/TOPK protein. Non-specific cytoplasmic staining was observed in human and mouse skeletal muscle and in mouse spleen by immunohistochemistry.

    Species Reactivity:

    Human, Mouse, Rat

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human PBK/TOPK protein.

    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 in vitro, presumably at Thr9 (5). Potential substrates of PBK/TOPK include p38 MAPK and c-Myc (3,4).
