Although formerly called MANSC (for motif at N terminus with seven cysteines) it has now been renamed by MANEC (motif at N terminus with eight cysteines) by Richard Mitter and Stephen Fitzgerald after the discovery of an eighth conserved cysteine. It is postulated that this domain may play a role in the formation of protein complexes involving various protease activators and inhibitors [1].

BPTI (bovine pancreatic trypsin inhibitor) is an extensively studied model structure. Certain family members are similar to the tick anticoagulant peptide (TAP, Swiss:P17726). This is a highly selective inhibitor of factor Xa in the blood coagulation pathways [1]. TAP molecules are highly dipolar [2], and are arranged to form a twisted two- stranded antiparallel beta-sheet followed by an alpha helix [1].
