TEAD2 (ETF, ETEF-1, TEF-4), together with TEAD1, defines a novel family of transcription factors, the TEAD family, highly conserved through evolution. TEAD proteins were notably found in Drosophila (Scalloped), C. elegans (egl -44), S. cerevisiae and A. nidulans. TEAD2 has been less studied than TEAD1 but a few studies revealed its role during development. TEAD2 is a member of the mammalian TEAD transcription factor family (initially named the transcriptional enhancer factor (TEF) family), which contain the TEA/ATTS DNA-binding domain. Members of the family in mammals are TEAD1, TEAD2, TEAD3, TEAD4.
