The AP-2 family of transcription factors
Dawid Eckert, Sandra Buhl, Susanne Weber, Richard Jäger, Hubert Schorle Genome Biology 2005, 6:246 (28 December 2005)
Abstract | Full text | PDF | PubMed | Cited on BioMed Central
|
Editor’s summary
AP-2 transcription factors are involved in cell-type-specific stimulation of proliferation and the suppression of terminal differentiation during embryonic development. Members of the family are found in mammals (with five different proteins in human and mice), frogs and fish, as well as protochordates, insects and nematodes.
