CREB-Binding-Protein

The CREB - binding protein ( CREB binding protein ), short- CBP is a coactivator of transcription.

CBP establishes a connection between the transcription factor CREB, and the transcription start point by a histone acetyltransferase (HAT, EC 2.3.1.48 ) changes the chromatin structure, which is loosened thereby. CBP shows homologies also acting as a HAT protein p300. CBP and p300 acetylate histones H3 and H4 preferred.

CBP is a coactivator of a general nature and interacts with transcription factors, for example.

Clinical Significance

Mutations in this gene are responsible for the Rubinstein - Taybi syndrome ( RTS).
