Binding of JMJD2D to p53.

<p>(<b>A</b>) Flag-tagged JMJD2D or HSPBAP1 were coexpressed with p53 in HEK293T cells. After anti-p53 immunoprecipitation (IP), coprecipitated proteins were revealed by anti-Flag immunoblotting (top panel). The bottom two panels show input levels of Flag-tagged proteins or p53. IgH, immunoglobulin heavy chain. (<b>B</b>) Indicated Flag-tagged JMJD proteins were coexpressed with p53 in HEK293T cells. After anti-Flag immunoprecipitation, coprecipitated p53 was detected by anti-p53 Western blotting (top panel). The middle and bottom panels show p53 and Flag-JMJD protein input levels, respectively. (<b>C</b>) HCT116 cell extracts were challenged with no, control or anti-JMJD2D antibodies and coprecipitated p53 detected by immunoblotting (top panel). The bottom panel shows that respective JMJD2D input levels were equal.
