Target Information
CREB (Cyclic AMP response element binding protein) is a 43 kDa basic/leucine zipper transcription factor that binds the cyclic AMP response element (CRE) and activates transcription in response to various extracellular signals such as neurotransmitters, hormones, membrane depolarization, and growth and neurotrophic factors. Activation of CREB depends on phosphorylation of serine 133. Phosphorylation occurs via p44/42 MAP kinase, p90RSK, p38 MAP kinase, and MSK1. Although CREB binds DNA independent of its phosphorylation state, only the phosphorylated form functions as a transcription factor. CREB binding protein (CBP), a transcriptional coactivator, binds CREB at the region of serine 133. CREB is involved in cellular processes including circadian rhythm synchronization, adipocyte differentiation, and learning and memory. In humans, the gene is located on chromosome 2q. Diseases associated with CREB dysfunction include Alzheimer’s disease, histiocytoma, and soft tissue melanoma.
