This protein binds the cAMP response element (CRE), a sequence present in many viral and cellular promoters. CREB stimulates transcription on binding to the CRE. This protein is stimulated by phosphorylation. Phosphorylation of both Ser-133 and Ser-142 in the SCN regulates the activity of CREB and participates in circadian rhythm generation. Phosphorylation of Ser-133 allows CREBBP binding. Transcription activation is enhanced by the TORC coactivators which act independently of Ser-133 phosphorylation. CREB1 is sumoylated by SUMO1. Sumoylation on Lys-304, but not on Lys-285, is required for nuclear localization of this protein. Sumoylation is enhanced under hypoxia, promoting nuclear localization and stabilization. Defects in CREB1 may be a cause of angiomatoid fibrous histiocytoma (AFH), a distinct variant of malignant fibrous histiocytoma that typically occurs in children and adolescents and is manifest by nodular subcutaneous growth.  A chromosomal aberration involving CREB1 is found in a patient with angiomatoid fibrous histiocytoma. Translocation t(2;22)(q33;q12) with CREB1 generates a EWSR1\/CREB1 fusion gene that is most common genetic abnormality in this tumor type. CREB1 exists some isoforms and range of calculated molecular weight of isoforms are 35-37 kDa and 25 kDa, but the modified CREB1 protein is about 43 kDa (PMID: 25883219 ).\n\u003cb\u003eSpecification\u003c\/b\u003e\nTested Reactivity: human, mouse, rat\nCited Reactivity: human, mouse, rat, rabbit\nHost \/ Isotype: Mouse \/ IgG1\nClass: Monoclonal\nType: Antibody\nImmunogen: CatNo: Ag2852 Product name: Recombinant human CREB1 protein Source: e coli. -derived, PGEX-4T Tag: GST Domain: 1-341 aa of BC010636 Sequence: MTMESGAENQQSGDAAVTEAENQQMTVQAQPQIATLAQVSMPAAHATSSAPTVTLVQLPNGQTVQVHGVIQAAQPSVIQSPQVQTVQSSCKDLKRLFSGTQISTIAESEDSQESVDSVTDSQKRREILSRRPSYRKILNDLSSDAPGVPRIEEEKSEEETSAPAITTVTVPTPIYQTSSGQYIAITQGGAIQLANNGTDGVQGLQTLTMTNAAATQPGTTILQYAQTTDGQQILVPSNQVVVQAASGDVQTYQIRTAPTSTIAPGVVMASSPALPTQPAEEAARKREVRLMKNREAARECRRKKKEYVKCLENRVAVLENQNKTLIEELKALKDLYCHKSD Predict reactive species\nFull Name: cAMP responsive element binding protein 1\nCalculated Molecular Weight: 341 aa, 35 kDa\nObserved Molecular Weight: 43-46 kDa\nGenBank Accession Number: BC010636\nGene Symbol: CREB1\nGene ID (NCBI): 1385\nRRID: AB_2918679\nConjugate: Unconjugated\nForm: Liquid\nPurification Method: Protein G purification\nUNIPROT ID: P16220\nStorage Buffer: PBS with 0.02% sodium azide and 50% glycerol, pH 7.3.\nStorage Conditions: Store at -20°C.
