Dot blot Use at an assay dependent concentration.


  • Function
    DNA-binding protein involved in cell cycle control. May act as a transcription activator. Component of the PRP19-CDC5L complex that forms an integral part of the spliceosome and is required for activating pre-mRNA splicing.
  • Tissue specificity
    Ubiquitously expressed in both fetal and adult tissues.
  • Involvement in disease
    A chromosomal aberration involving CDC5L is found in multicystic renal dysplasia. Translocation t(6;19)(p21;q13.1) with USF2.
  • Sequence similarities
    Belongs to the CEF1 family.
    Contains 2 HTH myb-type DNA-binding domains.
  • Post-translational
    Phosphorylated on serine and threonine residues. Phosphorylation on Thr-411 and Thr-438 is required for CDC5L-mediated mRNA splicing. Has no effect on subcellular location nor on homodimerization. Phosphorylated in vitro by CDK2. Phosphorylation enhances interaction with PPP1R8.
  • Cellular localization
    Nucleus. Nucleus speckle. Cytoplasm. May shuttle between cytoplasm and nucleus.

  • Immunoprecipitation analysis using ab51320 at 5ug/500ug RIPA lysate of HeLa cells. Immunoblot uses ab51320 at 1/100 dilution and anti-mouse IgG at 1/2500 as secondary.
  • Overlay histogram showing HeLa cells stained with ab51320 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab51320, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
