It is found associated with CBS domains Pfam:PF00571, as well as the CbiA domain Pfam:PF01656. The function of this domain is unknown. It is named the DRTGG domain after some of the most conserved residues. This domain may be very distantly related to a pair of CBS domains. There are no significant sequence similarities, but its length and association with CBS domains supports this idea (Bateman A, pers. obs.).

Pairs of these domains have been termed a Bateman domain [6]. CBS domains have been shown to bind ligands with an adenosyl group such as AMP, ATP and S-AdoMet [5]. CBS domains are found attached to a wide range of other protein domains suggesting that CBS domains may play a regulatory role making proteins sensitive to adenosyl carrying ligands. The region containing the CBS domains in Cystathionine-beta synthase is involved in regulation by S-AdoMet [4]. CBS domain pairs from AMPK bind AMP or ATP [5]. The CBS domains from IMPDH and the chloride channel CLC2 bind ATP [5].
