Summary: This gene encodes the adenovirus E1A-associated cellular p300 transcriptional co-activator protein. It functions as histone acetyltransferase that regulates transcription via chromatin remodeling and is important in the processes of cell proliferation and differentiation. It mediates cAMP-gene regulation by binding specifically to phosphorylated CREB protein. This gene has also been identified as a co-activator of HIF1A (hypoxia-inducible factor 1 alpha), and thus plays a role in the stimulation of hypoxia-induced genes such as VEGF. Defects in this gene are a cause of Rubinstein-Taybi syndrome and may also play a role in epithelial cancer. [provided by RefSeq, Jul 2008]

TonB; Periplasmic protein TonB, links inner and outer membranes [Cell wall/membrane/envelope biogenesis]

cd02337
Location:1668 → 1708

ZZ_CBP; Zinc finger, ZZ type. Zinc finger present in CBP/p300 and related proteins. The ZZ motif coordinates two zinc ions and most likely participates in ligand binding or molecular scaffolding. CREB-binding protein (CBP) is a large multidomain protein that ...
