  • Target

    • RelevanceThe gene for CDK2NA generates several transcripts/proteins which differ from each other in their first exons. Three of these transcripts are generated by alternative splicing (isoform 1 a.k.a p16INK4A, isoform 2 and isoform 3 a.k.a p12), two of which are known to function as inhibitors of CDK4 kinase. One other transcript that is generated from this gene contains an alternate reading frame (ARF), with the first exon located 20kb upstream of the remainder of the gene(isoform 4 a.k.a. p14ARF, p19ARF, ARF). In spite of the structural and some functional differences, all the proteins encoded by the CDKN2A gene are involved in cell cycle G1 control.

    • All lanes : Anti-CDKN2A/p19ARF antibody [5-C3] (ab26696)

      Lane 1 : Total cell lysate from NIH3T3 cells with Arf gene deleted
      Lane 2 : MEF total cell lysate

      Secondary
      anti-rat IgG-HRP

      Predicted band size : 17 kDa
      Observed band size : 19 kDa (why is the actual band size different from the predicted?)
    • Immunoprecipitation using anti-p19ARF 5C3. NIH3T3 cells expressing HA-p19ARF were incubated with a control rat IgG (lane 1) or anti-p19ARF 5C3 (2). Precipitated proteins were analysed by Western blot using anti-HA antibody.
    • Immunofluorescent detection of p19ARF. MEF cells (1 and 2) or NIH3T3 cells with arf gene deleted (3 and 4) were stained with anti-p19ARF 5C3 followed by a fluorescent-labelled anti-rat IgG (1 and 3) and Hoechst dye to visualise nuclei (2 and 4).
