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].

This protein is organised into an N-terminal kinase domain (KD, Pfam:PF00069) and a regulatory C-terminus, which contains an autoinhibitory domain (AID, this entry). This domain can form a compact domain that stabilizes the KD and binds to CBS-2 of the gamma-subunit [1-7].
