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 extracellular signals such as neurotransmitters, hormones, membrane depolarization, and growth or neurotrophic factors.
Activation of CREB depends on phosphorylation at serine 133 via p44/42 MAP kinase, p90RSK, p38 MAP kinase, and MSK1.
Only the phosphorylated form functions as a transcription factor by interacting with CREB binding protein (CBP).
CREB is involved in circadian rhythm synchronization, adipocyte differentiation, and learning and memory.
In humans, the CREB gene is located on chromosome 2q.
Dysfunction of CREB is associated with diseases such as Alzheimer’s disease, histiocytoma, and soft tissue melanoma.
