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-117 phosphorylation. Involved in different cellular processes including the synchronization of circadian rhythmicity and the differentiation of adipose cells.3 Publications

Sumoylated with SUMO1. Sumoylation on Lys-288, but not on Lys-269, is required for nuclear localization of this protein. Sumoylation is enhanced under hypoxia, promoting nuclear localization and stabilization (By similarity).By similarity
Stimulated by phosphorylation. Phosphorylation of both Ser-117 and Ser-126 in the SCN regulates the activity of CREB and participates in circadian rhythm generation. Phosphorylation of Ser-117 allows CREBBP binding. Phosphorylated upon calcium influx by CaMK4 and CaMK2 on Ser-117. CaMK4 is much more potent than CaMK2 in activating CREB. Phosphorylated by CaMK2 on Ser-126. Phosphorylation of Ser-126 blocks CREB-mediated transcription even when Ser-117 is phosphorylated. Phosphorylated by CaMK1. Phosphorylation of Ser-255 by HIPK2 in response to genotoxic stress promotes CREB1 activity, facilitating the recruitment of the coactivator CBP. Phosphorylated at Ser-117 by RPS6KA3, RPS6KA4 and RPS6KA5 in response to mitogenic or stress stimuli. CREBL2 positively regulates phosphorylation at Ser-117 thereby stimulating CREB1 transcriptional activity. In liver, phosphorylation is induced by fasting or glucagon in a circadian fashion (By similarity). Phosphorylated by TSSK4 on Ser-117 (By similarity).By similarity

Interacts with PPRC1. Binds DNA as a dimer. This dimer is stabilized by magnesium ions.

Interacts, through the bZIP domain, with the coactivators TORC1/CRTC1, TORC2/CRTC2 and TORC3/CRTC3. When phosphorylated on Ser-117, binds CREBBP.

Interacts (phosphorylated form) with TOX3. Binds to HIPK2 (By similarity).

Interacts with SGK1 (By similarity).

Interacts with CREBL2; regulates CREB1 phosphorylation, stability and transcriptional activity (By similarity).

Interacts with TSSK4; this interaction facilitates phosphorylation on Ser-117 (By similarity).

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:i61B4B4244FAB474B
