Figure 1From: Phylogenetic analysis of the human thyroglobulin regions The structure of the thyroglobulin protein. a) Structure of the human thyroglobulin protein. b) Structure of the zebrafish thyroglobulin protein. c) Structure of the amphioxus thyroglobulin-like protein. d) Structure of the sea urchin thyroglobulin-like protein. Blue: Tg1 domains, red: Tg2 domains, green: Tg3 domains, black: the ChEL domain. Magenta: the location of the thyroid hormone synthesis sites on the proteins (tyrosine residues).Back to article page
