Protein Family Models

This entry represents a pair of helices found at the N-terminus of some CBS domain proteins. A pair of these regions dimerise to form a four helical bundle. Proteins in this family have this region followed by two CBS domains and Pfam:PF03471. (from Pfam)

This small domain is found in a family of proteins with the Pfam:PF01595 domain and two CBS domains with this domain found at the C-terminus of the proteins, the domain is also found at the C terminus of some Na+/H+ antiporters. This domain is also found in CorC that is involved in Magnesium and cobalt efflux. The function of this domain is uncertain but might be involved in modulating transport of ion substrates.

CBS domains are small intracellular modules that pair together to form a stable globular domain [2]. This family represents a single CBS domain. 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]. Discovery and naming of the CBS domain. [1]. 9020585.
