CREBBP(redirected from CREB binding protein)
Also found in: Wikipedia.
CREBBPA gene on chromosome 16p13.3 that encodes a ubiquitously expressed protein involved in the transcriptional coactivation of various transcription factors. CREBBP acts as a scaffold to stabilise additional protein interactions with the transcription complex; it has intrinsic histone acetyltransferase activity, and acetylates both histone and non-histone proteins.
CREBBP mutations cause Rubinstein-Taybi syndrome (RTS); chromosomal translocations of CREBBP are associated with acute myeloid leukaemia.
