| Specificity: | The antibody detects a 43 kDa* protein corresponding to the molecular mass of CREB on SDS-PAGE immunoblots of human A431, Jurkat, and rat PC12 cells treated with Calyculin A, but is not observed after lambda phosphatase treatment. |
| Immunogen: | Phospho-CREB (Ser-271) synthetic peptide (coupled to carrier protein) corresponding to amino acids surrounding Ser-271 in human CREB. This sequence is well conserved in rat, mouse, chicken, and zebrafish CREB. The site has some homology to the conser |
| Post Translational Modifications | Stimulated by phosphorylation. Phosphorylation of both Ser-119 and Ser-128 in the SCN regulates the activity of CREB and participates in circadian rhythm generation. Phosphorylation of Ser-119 allows CREBBP binding. In liver, phosphorylation is induced by fasting or glucagon in a circadian fashion. CREBL2 positively regulates phosphorylation at Ser-119 thereby stimulating CREB1 transcriptional activity. Phosphorylated upon calcium influx by CaMK4 and CaMK2 on Ser-119. CaMK4 is much more potent than CaMK2 in activating CREB. Phosphorylated by CaMK2 on Ser-128. Phosphorylation of Ser-128 blocks CREB-mediated transcription even when Ser-119 is phosphorylated. Phosphorylated by CaMK1. Phosphorylation of Ser-257 by HIPK2 in response to genotoxic stress promotes CREB1 activity, facilitating the recruitment of the coactivator CBP. Phosphorylated at Ser-119 by RPS6KA3, RPS6KA4 and RPS6KA5 in response to mitogenic or stress stimuli. Phosphorylated by TSSK4 on Ser-119. Sumoylated with SUMO1. Sumoylation on Lys-290, but not on Lys-271, is required for nuclear localization of this protein. Sumoylation is enhanced under hypoxia, promoting nuclear localization and stabilization. |
| Function | 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. Transcription activation is enhanced by the TORC coactivators which act independently of Ser-119 phosphorylation. Involved in different cellular processes including the synchronization of circadian rhythmicity and the differentiation of adipose cells. Regulates the expression of apoptotic and inflammatory response factors in cardiomyocytes in response to ERFE-mediated activation of AKT signaling. |
