Fig. 8From: Whole genome level analysis of the DEATH protein superfamily in sheep (Ovis aries) and their coordination relationship in regulating lactationThe 3D structures of the DD, CARD, DED, and PYRIN domains were highly evolutionarily conserved. a–d 3D structures of the DD, CARD, DED, and PYRIN domains from human, mouse, zebrafish, and frog/fly/γ herpes virus and their structural alignments. The cylinder elements in each structure represented α-helices. e RMSD matrix of the DD, CARD, DED, and PYRIN domains of different organismsBack to article page
