摘要:
The p300 protein is one of more than 15 known mammalian HATs. We have used mice that carry a mutant allele of the p300 gene, which encodes a full-length protein that, however, lacks detectable acetyltransferase (AT)-activity and that acts in a dominant-negative manner. In addition, the allele is conditional, so that it can be expressed in a tissue-specific manner with the help of mice that express Cre-recombinase. Expression of the mutant allele specifically in B-cells, using CD19-cre mice, results in premature death with full penetrance from an autoimmune disease that closely mimics systemic lupus erythematosus (SLE) in its pathological manifestations.
