The function of Ensembl gene identifier ENSG00000118260 (CREB1, cAMP responsive element binding protein 1) is as follows. Phosphorylation-dependent transcription factor that stimulates transcription upon binding to the DNA cAMP response element (CRE), a sequence present in many viral and cellular promoters (By similarity). Transcription activation is enhanced by the TORC coactivators which act independently of Ser-119 phosphorylation (PubMed:14536081). Involved in different cellular processes including the synchronization of circadian rhythmicity and the differentiation of adipose cells (By similarity). Regulates the expression of apoptotic and inflammatory response factors in cardiomyocytes in response to ERFE-mediated activation of AKT signaling (By similarity). {ECO:0000250|UniProtKB:P27925, ECO:0000250|UniProtKB:Q01147, ECO:0000269|PubMed:14536081}.
