The SANTA domain (SANT Associated domain) is approximately 90 amino acids in length and is conserved in Eukaryota. It is sometimes found in association with the SANT domain (Pfam:PF00249, also known as Myb-like DNA-binding domain) implying a putative function in regulating chromatin remodelling [1]. Sequence analysis has showed that the SANTA domain is likely to form four central beta-sheets with three flanking alpha- helixes [1]. Many conserved hydrophobic residues are present which implying a possible role in protein-protein interactions [1].	Domain
