1/500 - 1/1000. Detects a band of approximately 21 kDa (predicted molecular weight: 21 kDa).
FunctionThis protein binds the cAMP response element (CRE) (consensus: 5'-GTGACGT[AC][AG]-3'), a sequence present in many viral and cellular promoters. Represses transcription from promoters with ATF sites. It may repress transcription by stabilizing the binding of inhibitory cofactors at the promoter. Isoform 2 activates transcription presumably by sequestering inhibitory cofactors away from the promoters.
Sequence similaritiesBelongs to the bZIP family. ATF subfamily. Contains 1 bZIP domain.
