Transthyretin_like. This domain is present in the transthyretin-like protein (TLP) family which includes transthyretin (TTR) and a transthyretin-related protein called 5-hydroxyisourate hydrolase (HIUase). TTR and HIUase are homotetrameric proteins with each subunit consisting of eight beta-strands arranged in two sheets and a short alpha-helix. The central channel of the tetramer contains two independent binding sites, each located between a pair of subunits. TTR transports thyroid hormones and retinol in the blood serum of vertebrates while HIUase catalyzes the second step in a three-step ureide pathway. TTRs are highly conserved and found only in vertebrates while the HIUases are found in a wide range of bacterial, plant, fungal, slime mold and vertebrate organisms.
No pairwise interactions are available for this conserved domain.
Tips:  If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position. The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs. Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below. Range on the Protein: Protein ID Protein Position Domain Position:
