Gene Information

human ... CREB1(1385)

Specificity

Recognizes phosphorylated Serine133 in cAMP response element binding protein (CREB). By immunoblotting the antibody shows a 5-10 fold increase in staining of a 43 kDa protein after treatment of cells with agents that increase intracellular cAMP. The antibody also recognizes phosphorylated ATF-1 due to a common epitope. The antibody has been preabsorbed with unphosphorylated peptide and will prove to be useful for the investigation of CREB phosphorylation.

Immunogen

Epitope: pSer133
Phosphopeptide conjugated to KLH.

Application

Many organisms exhibit temporal rhythms in gene expression that propel diurnal cycles in physiology. In the liver of mammals, these rhythms are controlled by transcription-translation feedback loops of the core circadian clock and by feeding-fasting cycles. To better understand the
