H3mm18 interacts with H3.3 chaperones. (A) Coimmunoprecipitation with FLAG-tagged DAXX. NIH3T3 cells expressing the N-terminally EGFP-tagged histone H3.1, H3.3 or H3mm18 were infected with retroviral vectors for C-terminally FLAG-tagged DAXX, and then treated with 5 μM MG132 for 6 h. Chromatin-unbound fractions were prepared and subjected to the immunoprecipitation (IP) assay using the anti-FLAG antibody. Input fractions and precipitates were analyzed by western blotting using the indicated antibodies. (B) IP for interaction with endogenous DAXX. NIH3T3 cells expressing the N-terminally EGFP-tagged histone H3.1, H3.3 or H3mm18 were treated with 5 μM MG132 for 6 h and subjected to IP, using anti-GFP or anti-H3mm18 antibodies.
