ID:CR3L3_HUMAN DESCRIPTION: RecName: Full=Cyclic AMP-responsive element-binding protein 3-like protein 3; Short=cAMP-responsive element-binding protein 3-like protein 3; AltName: Full=Transcription factor CREB-H; Contains: RecName: Full=Processed cyclic AMP-responsive element-binding protein 3-like protein 3; FUNCTION: Transcription factor that may act during endoplasmic reticulum stress by activating unfolded protein response target genes. Activated in response to cAMP stimulation. In vitro, binds to the cAMP response element (CRE) and box-B element. Activates transcription through box-B element. Activates transcription through CRE (By similarity). Seems to function synergistically with ATF6. In acute inflammatory response, may activate expression of acute phase response (APR) genes. May be involved in growth suppression. SUBUNIT: Binds DNA as a dimer (By similarity). Probably homodimerizes. Probably forms a heterodimer with ATF6. Interacts with ATF6. INTERACTION: P18850:ATF6; NbExp=2; IntAct=EBI-852194, EBI-852157; SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Single-pass type II membrane protein. SUBCELLULAR LOCATION: Processed cyclic AMP-responsive element- binding protein 3-like protein 3: Nucleus. Note=Under ER stress the cleaved N-terminal cytoplasmic domain translocates into the nucleus. TISSUE SPECIFICITY: Exclusively expressed in liver. Underexpressed in hepatocellular carcinoma tissues. PTM: Controlled by regulated intramembrane proteolysis (RIP). Following ER stress a fragment containing the cytoplasmic transcription factor domain is released by proteolysis. The cleavage seems to be performed sequentially by site-1 and site-2 proteases (PS1 and PS2). PTM: N- and O-glycosylated. N-glycosylation is required for optimal proteolytic activation. O-glycosylated with core 1 or possibly core 8 glycans. SIMILARITY: Belongs to the bZIP family. ATF subfamily. SIMILARITY: Contains 1 bZIP (basic-leucine zipper) domain. SEQUENCE CAUTION: Sequence=BAD18804.1; Type=Frameshift; Positions=445; Sequence=BAD18804.1; Type=Miscellaneous discrepancy; Note=Aberrant splicing;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
