. "An uncharacterized alpha helical domain containing a highly conserved ER motif and typically found as a tandem duplication. Contextual analysis suggests that it functions in a distinct peptide synthesis/modification system comprising of a transglutaminase, a peptidase of the NTN-hydrolase superfamily, an active and inactive circularly permuted ATP-grasp domains and a transglutaminase fused" .
