In molecular biology, the BSD domain is an approximately 60 amino acid long protein domain named after the BTF2-like transcription factors, Synapse-associated proteins and DOS2-like proteins in which it is found. Additionally, it is also found in several hypothetical proteins. The BSD domain occurs in one or two copies in a variety of species ranging from primal protozoan to human. It can be found associated with other domains such as the BTB domain or the U-box in multidomain proteins. The function of the BSD domain is as yet unknown.[1]

Secondary structure prediction indicates the presence of three predicted alpha helices, which probably form a three-helical bundle in small domains. The third predicted helix contains neighbouring phenylalanine and tryptophan residues - less common amino acids that are invariant in all the BSD domains identified and that are the most striking sequence features of the domain.[1]

Some proteins known to contain one or two BSD domains are listed below:

  • Various Arabidopsis thaliana (Mouse-ear cress) hypothetical proteins.
