This domain is about 90 residues in length and is often found associated with the Pfam:PF02213 domain. The function of this domain is uncertain. It is possible that this domain is involved in DNA binding as it has three conserved positively charged residues, hence this domain has been named the plus-3 domain. It is found in yeast Rtf1 which may be a transcription elongation factor [1].	Domain
