In this study , we demonstrate that the involved inducible C / EBP isoforms are C / EBP beta and C / EBP delta , and together they control the high level induction of the alpha 1 acid glycoprotein gene in response to inflammatory signals . ^^^ Transient transfections using expression vectors of C / EBP alpha , C / EBP beta and C / EBP delta have shown that while individually all three isoforms can transactivate the alpha 1 acid glycoprotein chloramphenicol acetyltransferase gene transcription , co expression of C / EBP alpha and C / EBP beta isoforms results in lower levels of reporter gene expression than the levels predicted from their additive transactivation level . ^^^ Higher than additive levels of reporter gene expression are observed when combinations of C / EBP delta and C / EBP beta or C / EBP delta and C / EBP alpha are used . ^^^ Together , these data demonstrate that C / EBP beta and C / EBP delta are the major proteins responsible for the acute phase induction of alpha 1 acid glycoprotein gene expression and they require phosphorylation for transactivation potential . . ^^^

Early responses of trans activating factors to growth hormone in preadipocytes : differential regulation of CCAAT enhancer binding protein beta ( C / EBP beta ) and C / EBP delta . ^^^ Concomitant with the translationally activated increase in C / EBP beta , a GH dependent increase was observed in C / EBP delta transcription . ^^^ This was accompanied by an increase in mRNA for C / EBP delta , which was superinduced by cycloheximide and , unlike the increase in C / EBP beta protein , was not observed with insulin . ^^^ Thus GH exerts its effects on C / EBP isoforms at two levels : transcriptional activation of C / EBP delta and translational activation of C / EBP beta . ^^^ It is proposed that GH dependent phosphorylation results in the efficient translation of 40 C / EBP beta and 23 C / EBP beta ( the mouse homolog of the inhibitor liver enriched inhibitory protein ) , and that together with the induction of C / EBP delta , these may be involved in initiating the adipocyte differentiation program . . ^^^

IL 6 is able to activate the hsp 90 gene promoter directly ; this activation can also be achieved by overexpressing either of the transcription factors NF IL 6 or NF IL 6 beta whose synthesis is induced by IL 6 treatment . ^^^ Hence the induction of hsp 90 protein accumulation by IL 6 is likely to be dependent on the enhanced activity of the hsp 90 beta gene promoter produced by increased levels of NF IL 6 and / or NF IL 6 beta . ^^^

We have identified and characterized putative zebrafish orthologs of mammalian C / EBP alpha , beta , gamma , and delta using low stringency hybridization screening and computer searches of the GenBank EST database . c / ebpa and g were mapped within 1 cM of each other on linkage group ( LG ) 7 , syntenic with human CEBPA and G genes on chromosome 19 . c / ebpb was mapped to LG 8 , and c / ebpd was mapped to LG 24 , on the same LG as a recently identified unique c / ebp in zebrafish , c / ebp1 . ^^^

By combining genetic studies and footprinting analyses , we demonstrate that regulated expression of the CytR controlled cdd promoter requires three CRP binding sites : a high affinity site ( CRP 1 ) and two overlapping low affinity sites ( CRP 2 and CRP 3 ) centred at positions 41 , 91 and 93 , respectively . ^^^ Moreover , mutant cdd promoters in which CRP 2 and CRP 3 have been deleted are partially regulated by CytR , and cAMP CRP and CytR still bind cooperatively to these promoters . ^^^

CRP 2 is identical to the protein described recently by other groups as NF IL 6 , LAP , IL 6DBP , and AGP / EBP , whereas CRP 1 and CRP 3 represent novel proteins . ^^^ Three genes were isolated that encode bZIP DNA binding proteins ( designated CRP 1 , CRP 2 , and CRP 3 ) with strong amino acid sequence similarities to the C / EBP binding domain . ^^^ CRP 2 is identical to the protein described recently by other groups as NF IL 6 , LAP , IL 6DBP , and AGP / EBP , whereas CRP 1 and CRP 3 represent novel proteins . ^^^
