Our Abpromise guarantee covers the use of ab28848 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ELISA 1/20000.
IHC-P Use at an assay dependent concentration.
IP Use at an assay dependent concentration.
WB 1/500 - 1/1000. Detects a band of approximately 52 kDa (predicted molecular weight: 52 kDa).


  • 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.
  • Post-translational
    Phosphorylation of Thr-69 and Thr-71 by MAPK14 causes increased transcriptional activity. Also phosphorylated and activated by JNK.
