WebJul 22, 2008 · Abstract. CREB is a cAMP- and calcium-responsive transcriptional activator that is required for islet beta cell proliferation and survival. Glucose and incretin hormones elicit beta cell insulin secretion and promote synergistic CREB activity by inducing the nuclear relocalization of TORC2 (also known as Crtc2), a coactivator for CREB. WebMar 7, 2005 · Thus, depending on cellular context, CREB activity may be targeted to certain genes at the level of promoter occupancy, Ser-133 phosphorylation, or recruitment of the transcriptional apparatus. Here, we use multiple independent high-throughput techniques to examine how CREB functions in different tissues. Our studies indicate that signal ...
