TAF homology
SMART accession number:SM00549
Description: Domain in Drosophila nervy, CBFA2T1, human TAF105, human TAF130, and Drosophila TAF110. Also known as nervy homology region 1 (NHR1).
Interpro abstract (IPR003894):

The TAF homology (TAFH) or Nervy homology region 1 (NHR1) domain is a domain of 95-100 amino acids present in eukaryotic proteins of the MTG/ETO family and whereof the core ~75-80 residues occur in TAF proteins. The transcription initiation TFIID complex is composed of TATA binding protein (TBP) and a number of TBP-associated factors (TAFs). The TAFH/NHR1 domain is named after fruit fly TATA-box-associated factor 110 (TAF110), human TAF105 and TAF130, and the fruit fly protein Nervy, which is a homologue of human MTG8/ETO [(PUBMED:9447981), (PUBMED:9790752)]. The human eight twenty-one (ETO, MTG8 or CBFA2T1) and related myeloid transforming gene products MTGR1 and MTG16 as well as the Nervy protein contain the NHR1-4 domains. The NHR1/TAFH domain occurs in the N-terminal part of these proteins, while a MYND-type zinc finger forms the NHR4 domain [(PUBMED:12559562)]. The TAFH/NHR1 domain can be involved in protein-protein interactions, e.g in MTG8/ETO with HSP90 and Gfi-1 [(PUBMED:10076566)].
