 24-144 4.49e-79

Transthyretin (TTR) is a 55 kDa protein responsible for the transport of thyroid hormones and retinol in vertebrates. TTR distributes the two thyroid hormones T3 (3,5,3'-triiodo-L-thyronine) and T4 (Thyroxin, or 3,5,3',5'-tetraiodo-L-thyronine), as well as retinol (vitamin A) through the formation of a macromolecular complex that includes each of these as well as retinol-binding protein. Misfolded forms of TTR are implicated in the amyloid diseases familial amyloidotic polyneuropathy and senile systemic amyloidosis. TTR forms a homotetramer 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, which differ in their ligand binding affinity. A negative cooperativity has been observed for the binding of T4 and other TTR ligands. A fraction of plasma TTR is carried in high density lipoproteins by binding to apolipoprotein AI (apoA-I). TTR is able to proteolytically process apoA-I by cleaving its C-terminus; therefore TTR has protease activity in addition to its function in protein transport.

hydroxyisourate hydrolase; Members of this family, hydroxyisourate hydrolase, represent a distinct clade of transthyretin-related proteins.

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.

HIUase (5-hydroxyisourate hydrolase) catalyzes the second step in a three-step ureide pathway in which 5-hydroxyisourate (HIU), a product of the uricase (urate oxidase) reaction, is hydrolyzed to 2-oxo-4-hydroxy-4-carboxy-5-ureidoimidazoline (OHCU). HIUase has high sequence similarity with transthyretins and is a member of the transthyretin-like protein (TLP) family. HIUase is distinguished from transthyretins by a conserved signature motif at its C-terminus that forms part of the active site. In HIUase, this motif is YRGS, while transthyretins have a conserved TAVV sequence in the same location. Most HIUases are cytosolic but in plants and slime molds, they are peroxisomal based on the presence of N-terminal periplasmic localization sequences. HIUase forms a homotetramer 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.
