CREBBP

A 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.

Molecular pathology
CREBBP mutations cause Rubinstein-Taybi syndrome (RTS); chromosomal translocations of CREBBP are associated with acute myeloid leukaemia.

One candidate protein for this process is known as CBP, or CREB binding protein, which is central in the biochemistry of cellular survival.
