This antibody is designed, produced, and validated as part of a collaboration between Rockland and the National Cancer Institute (NCI). PBK1 protein (also known as Ribosomal L1 domain-containing protein 1, cellular senescence-inhibited gene protein, and CATX-11) was isolated from highly invasive first trimester trophoblast cells and has been proposed to regulate their naturally occurring invasive behavior (Huch et al., 1998). PBK1 was also found to be over-expressed in non-small-cell lung cancer (NSCLC) cells (Petroziello et al., 2004). A recent study suggests that PBK1 may up-regulate the urokinase-type plasminogen activator (uPA) gene, which plays an important role in cellular matrix degradation and activation of other protease systems involved in cell invasion (Tong et al., 2005). The cellular localization dynamics of PBK1, as well as the data from its yeast homologue (Cic1p/Nsa3p) suggest that PBK1 is essential for ribosome biogenesis (Fatica et al., 2003). Thus, PBK1 could be controlling cell proliferation by regulating the level of ribosome production. It is hypothesized that PBK1 is involved in regulating both, cell proliferation and invasiveness, therefore playing a dual function in cancer cells transformation.
This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to an internal sequence of human PBK1.
