General notes
Cyclic AMP-responsive enhancer binding protein (CREB) binding protein (CBP) and p300 are closely related transcriptional coactivators that have been shown to directly interact with many different DNA-binding transcription factors including nuclear hormone receptors, CREB (cyclic AMP-responsive enhancer binding protein), c-Fos, c-Jun/v-Jun, c-Myb/v-Myb, TFIIB and MyoD.Both CBP and p300 have been shown to display histone acetyltransferase (HAT) activity, capable of acetylating all four core histone particles in nucleosomes.As a result of HAT activity, it has been suggested CBP and p300 may play a direct role in activating chromatin for transcription.Single point mutations in CBP have been proposed as causative factors in the developmental abnormalities of Rubinstein-Taybi syndrome (RTS).Although both CBP and p300 appear to function similarly, the inability of p300 to rescue CBP malfunction iRTS suggests intrinsic functional differences between CBP and p300.

Immunoprecipitation - Anti-CREBBP antibody - ChIP Grade (ab10489)
ab10489 immunoprecipitating CREBBP at 6 µg/ml lysate.
Lane 1: Anti-CREBBP antibody ab10489 in HeLa whole cell extract (1 mg per IP reaction; 20% of IP loaded).
Lane 2: Anti-CREBBP antibody ab10490 in HeLa whole cell extract (1 mg per IP reaction; 20% of IP loaded).
Lane 3: IgG control.
For blotting immunoprecipitated CREBBP, ab10489 was used at 1 µg/mL.
Detection: Chemiluminescence with an exposure time of 30 seconds.

ChIP - Anti-CREBBP antibody - ChIP Grade (ab10489)Sonicated Chromatin prepared from U2OS cells was subjected to the ChIP procedure with ab10489 to CREBBP. Immunoprecipitated chromatin was analysed in the promoter region of c-FOS (active) and in exon 2 of MYO-D (inactive), values are % of inputs. 2–4 µg of ab10489 and 1-2x106 cells were used in each ChIP experiment.
