Tri-KIX +/- c-Myb MEFs


ABSTRACT: Transcription profiling by array of wild type and p300 KIX/KIX; CBP +/KIX primary mouse embryonic fibroblasts (MEFs) transduced with either MSCV-c-Myb_IRES-GFP or MSCV-IRES-GFP retrovirus to determine the effect of mutating the KIX domain of CBP and p300 on c-Myb regulated gene expression. CBP KIX mutation (MGI:3578129) and p300 KIX mutation (MGI:3578128).

Genetic interaction between mutations in c-Myb and the KIX domains of CBP and p300 affects multiple blood cell lineages and influences both gene activation and repression.

Adult blood cell production or definitive hematopoiesis requires the transcription factor c-Myb. The closely related KAT3 histone acetyltransferases CBP (CREBBP) and p300 (EP300) bind c-Myb through their KIX domains and mice homozygous for a p300 KIX domain mutation exhibit multiple blood defects. Perplexingly, mice homozygous for the same KIX domain mutation in CBP have normal blood. Here we test the hypothesis that the CBP KIX domain contributes subordinately to hematopoiesis via a genetic int  ...[more]
