BSD: a novel domain in transcription factors and synapse-associated proteins.
This article describes a novel domain, BSD, that is present in basal transcription factors, synapse-associated proteins and several hypothetical proteins. It occurs in a variety of species ranging from primal protozoan to human. The BSD domain is characterized by three predicted alpha helices, which probably form a three-helical bundle, as well as by conserved tryptophan and phenylalanine residues, located at the C terminus of the domain.
