The 'bivalent Mical/EHBP Rab binding' (bMERB) domain is a Rab effector domain that is present in proteins of the Mical and EHBP families, both known to act in endosomal trafficking. The bMERB domain displays a preference for Rab8 family proteins (Rab8, 10, 13 and 15) and at least some of the bMERB domains contain two separate binding sites for Rab-proteins, allowing Micals and EHBPs to bind two Rabs simultaneously. The strong similarity between the two binding sites within one bMRB domain strongly suggests an evolutionarily development via duplication of a common ancestor supersecondary structure element. The bMERB domain has a completely alpha-helical fold consisting of a central helix and N- and C-terminal helices folding back on this central helix [1].

The CH domain is involved in actin binding in some members of the family. However in calponins there is evidence that the CH domain is not involved in its actin binding activity [4]. Most member proteins have from two to four copies of the CH domain, however some proteins such as calponin and Swiss:P15498 have only a single copy.
