Our Abpromise guarantee covers the use of ab28812 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/500 - 1/1000. Detects a band of approximately 55 kDa (predicted molecular weight: 52 kDa).|
|IHC-P||Use at an assay dependent concentration.|
|IP||Use at an assay dependent concentration.|
FunctionTranscriptional activator, probably constitutive, which binds to the cAMP-responsive element (CRE) (consensus: 5'-GTGACGT[AC][AG]-3'), a sequence present in many viral and cellular promoters. Interaction with JUN redirects JUN to bind to CRES preferentially over the 12-O-tetradecanoylphorbol-13-acetate response elements (TRES) as part of an ATF2/JUN complex.
Tissue specificityAbundant expression seen in the brain.
Sequence similaritiesBelongs to the bZIP family. ATF subfamily.
Contains 1 bZIP domain.
Contains 1 C2H2-type zinc finger.
modificationsPhosphorylation of Thr-69 and Thr-71 by MAPK14 causes increased transcriptional activity. Also phosphorylated and activated by JNK.
