GenAge entry for CREBBP (Homo sapiens)

Gene name (HAGRID: 64)

HGNC symbol: CREBBP
Aliases: RTS; CBP; KAT3A; RSTS
Common name: CREB binding protein

Potential relevance to the human ageing process

Main reason for selection: Entry selected based on evidence linking the gene product to the regulation or control of genes previously linked to ageing
Description: A transcriptional regulatory protein, CREBBP acetylates histones and mediates cAMP-gene regulation by binding to phosphorylated CREB1. CREBBP null mice die during embryogenesis, but heterozygous animals exhibit lipodystrophy, have increased insulin (INS) and leptin (LEP) sensitivity, and appear to be protected from weight gain induced by a high-fat diet [429]. In humans, defects in CREBBP have been associated with Rubinstein-Taybi syndrome [428]. Its important roles in transcriptional regulation and its large number of interacting partners suggest CREBBP might potentially be involved in some aspects of ageing.
