TLDR
The transcription factor CREB functions in glucose homeostasis, growth-factor-dependent cell survival, and has been implicated in learning and memory, and how is specificity achieved in these signalling pathways?
Abstract
The transcription factor CREB -- for 'cyclic AMP response element-binding protein' -- functions in glucose homeostasis, growth-factor-dependent cell survival, and has been implicated in learning and memory. CREB is phosphorylated in response to various signals, but how is specificity achieved in these signalling pathways?

Molecular mechanisms controlling the localisation of protein kinase A.

TL;DR: This review presents an integrated overview on molecular mechanisms of PKA regulatory and catalytic subunit localisation in both yeast and multicellular organisms and focuses in more detail on recent advances in the unicellular eukaryote Saccharomyces cerevisiae.

Tyrosine hydroxylase transcription depends primarily on cAMP response element activity, regardless of the type of inducing stimulus.

TL;DR: It is found that basal transcription depends on transcription factor activity at the partial dyad, CRE, and AP1 elements, with only small contributions from the AP1 or hypoxia response element 1 (HRE1) elements, regardless of inducing stimulus.

Low Concentrations of Bisphenol A Induce Mouse Spermatogonial Cell Proliferation by G Protein–Coupled Receptor 30 and Estrogen Receptor-α

TL;DR: The data suggest that low concentrations of BPA activate the PKG and EGFR/ERK/c-fos pathways through a cross-talk between GPR30 and ER-α, which in turn stimulates GC-1 cell proliferation.

Platelet-activating factor mediates MMP-2 expression and activation via phosphorylation of cAMP-response element-binding protein and contributes to melanoma metastasis.

TL;DR: PAF acts as a promoter of melanoma metastasis in vivo and it is proposed that metastatic melanoma cells overexpressing CREB/ATF-1 are better equipped than nonmetastatic cells to respond to PAF within the tumor microenvironment.

Cyclic AMP stimulates somatostatin gene transcription by phosphorylation of CREB at serine 133

TL;DR: Results suggest that phosphorylation of CREB may stimulate transcription by a mechanism other than by simply providing negative charge, as CREB mutants containing acidic residues in place of the Ser-133 phosphoacceptor were also transcriptionally inactive.
Journal ArticleDOI

Phosphorylated CREB binds specifically to the nuclear protein CBP

TL;DR: It is proposed that CBP may participate in cAMP-regulated gene expression by interacting with the activated phosphorylated form of CREB, which is activated as a result of phosphorylation by protein kinase A7.
Journal ArticleDOI

Cell survival promoted by the Ras-MAPK signaling pathway by transcription-dependent and -independent mechanisms.

TL;DR: The findings suggest that the MAPK signaling pathway promotes cell survival by a dual mechanism comprising the posttranslational modification and inactivation of a component of the cell death machinery and the increased transcription of pro-survival genes.

Deficient long-term memory in mice with a targeted mutation of the cAMP-responsive element-binding protein

TL;DR: Consistent with models claiming a role for long-term potentiation (LTP) in memory, LTP in hippocampal slices from CREB mutants decayed to baseline 90 min after tetanic stimulation, however, paired-pulse facilitation and posttetanic potentiation are normal.
Journal ArticleDOI

Nuclear protein CBP is a coactivator for the transcription factor CREB

TL;DR: Fluorescence anisotropy measurements are used to define the equi-librium binding parameters of the phosphoCREB:CBP interaction and report here that CBP can activate transcription through a region in its carboxy terminus.
