Description

Background

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.

Application Note

This affinity purified antibody has been tested for use in ELISA, immunoprecipitation, immunofluorescence microscopy and western blotting.  Specific conditions for reactivity should be optimized by the end user.  Expect a band approximately 55 kDa in size corresponding to PBK1 by western blotting in the appropriate cell lysate or extract.  This antibody is capable of detecting both over-expressed and endogenous PBK1. For immunofluorescence microscopy, fix cells with methanol.

Purity/Specificity

This product was affinity purified from monospecific antiserum by immunoaffinity chromatography. This antibody is specific for human PBK1 protein.  A BLAST analysis was used to suggest limited cross-reactivity with PBK1 from mouse based on a 75% homology with the immunizing sequence.  Cross-reactivity with PBK1 from other sources has not been determined.
