CREB proteins are activated by phosphorylation from various kinases, including PKA, and Ca /calmodulin-dependent protein kinases on the Serine 133 residue. When activated, CREB protein recruits other transcriptional coactivators to bind to CRE promoter 5’ upstream region. Hydrophobic leucine amino … See more CREB-TF (CREB, cAMP response element-binding protein) is a cellular transcription factor. It binds to certain DNA sequences called cAMP response elements (CRE), thereby increasing or decreasing the See more The following genes encode CREB or CREB-like proteins: • CREB1 (CREB1) • CREB2 renamed ATF4 (ATF4 See more CREB has many functions in many different organs, and some of its functions have been studied in relation to the brain.
