Structural and functional aspects of winged-helix domains at the core of transcription initiation complexes

Transcription. 2012 Jan-Feb;3(1):2-7. doi: 10.4161/trns.3.1.18917.

Abstract

The winged helix (WH) domain is found in core components of transcription systems in eukaryotes and prokaryotes. It represents a sub-class of the helix-turn-helix motif. The WH domain participates in establishing protein-DNA and protein-protein-interactions. Here, we discuss possible explanations for the enrichment of this motif in transcription systems.
