Distinct functions of three members of the vertebrate ATF-2 family. (A) Homology between three members of the vertebrate ATF-2 family. (B) Two different functions of the ATF-2 transcription factor family. ATF-2 activates transcription in response to various stresses by interaction with the coactivator, CBP, which induces the acetylation of histones. In the absence of stress, ATF-7 silences transcription via interaction with the histone H3-K9 trimethyltransferase ESET (SETDB1), which forms a heterochromatin-like structure.
