This antibody does not cross-react with other ATF\/CREB family members. Non-specific staining of components along the retinotectal pathway was observed by immunofluorescence in fixed frozen mouse tissue. Non-specific signal is observed in formaldehyde fixed frozen mouse retina by immunofluorescence.\nSpecies Reactivity: Human, Mouse, Rat, Monkey, D. melanogaster\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nThe recombinant chimeric antibody is engineered from CREB (48H2) Rabbit mAb #9197 according to animal-free protocols. This chimeric antibody retains its antigen-binding Fab regions from the original rabbit monoclonal antibody but contains a horse-derived Fc domain. When multiplexing, Fc-directed rabbit secondary antibodies are required to detect rabbit-host primary antibodies. The parent antibody, CREB (48H2) Rabbit mAb #9197, is produced by immunizing animals with a recombinant protein specific to the amino terminus of human CREB-1 protein. The epitope has been mapped to residues surrounding Glu21.\n\u003cb\u003eBackground\u003c\/b\u003e\nCREB is a bZIP transcription factor that activates target genes through cAMP response elements. CREB is able to mediate signals from numerous physiological stimuli, resulting in regulation of a broad array of cellular responses. While CREB is expressed in numerous tissues, it plays a large regulatory role in the nervous system. CREB is believed to play a key role in promoting neuronal survival, precursor proliferation, neurite outgrowth, and neuronal differentiation in certain neuronal populations (1-3). Additionally, CREB signaling is involved in learning and memory in several organisms (4-6). CREB is able to selectively activate numerous downstream genes through interactions with different dimerization partners. CREB is activated by phosphorylation at Ser133 by various signaling pathways, including Erk, Ca , and stress signaling. Some of the kinases involved in phosphorylating CREB at Ser133 are p90RSK, MSK, CaMKIV, and MAPKAPK-2 (7-9).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nactive transcription factor CREB; cAMP responsive element binding protein 1; cAMP-response element-binding protein-1; cAMP-responsive element-binding protein 1; CREB; CREB-1; CREB1; cyclic adenosine 3',5'-monophosphate response element binding protein; cyclic adenosine 3',5'-monophosphate response element-binding protein CREB; Cyclic AMP-responsive element-binding protein 1; MGC9284; transactivator protein\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk Dm\nSENSITIVITY: Endogenous\nSource\/Isotype: Horse chimeric IgG4","brand":"CST","offers":[{"title":"Default Title","offer_id":46800297590953,"sku":"65363S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-65363s","provider":"Iright","version":"1.0","type":"link"}
