This is the SEP domain found in Spt20 proteins from both human and yeast. The Spt20 protein is part of the SAGA complex which is a large complex mediating histone deacetylation. Yeast Spt20 has been shown to play a role in structural integrity of the SAGA complex as as no intact SAGA could be purified in spt20 deletion strains [1]. Spt20 is indispensable under endoplasmic reticulum (ER) stress conditions, being involved in the regulation of stress-responsive genes transcription. This domain interacts with LisH motif helices of Taf5 [2,3].
Zinc finger present in dystrophin, CBP/p300. ZZ in dystrophin binds calmodulin. Putative zinc finger; binding not yet shown. Four to six cysteine residues in its sequence are responsible for coordinating zinc ions, to reinforce the structure [2].
This SWIRM domain is a small alpha-helical domain of about 85 amino acid residues found in chromosomal proteins. It contains a helix-turn helix motif and binds to DNA [1].
This domain is found in human Transcriptional adapter 2-alpha (TADA2A) and similar eukaryotic proteins. TADA2A is a component of the ATAC complex that plays a role in chromatin remodelling. This domain is predicted to adopt an alpha-beta structure.
Bromodomains are 110 amino acid long domains, that are found in many chromatin associated proteins. Bromodomains can interact specifically with acetylated lysine [3].

This family includes the Spt3 yeast transcription factors and the 18kD subunit from human transcription initiation factor IID (TFIID-18). Determination of the crystal structure reveals an atypical histone fold [1]
