Identified on 1942, Human transthyretin (TTR) ([[1dvq]]) is a transport protein encoded by the TTR gene, located on chromosome 18 <ref> Wallace MR, Naylor SL, Kluve-Beckerman B, Long GL, McDonald L, Shows TB, Benson MD, Localization of the human prealbumin gene to chromosome 18, Biochem Biophys Res Commun, 1985;129:753–758 doi:https://doi.org/10.1016/0006-291X(85)91956-4 </ref>. It is mainly present in the plasma and synthetized by the liver, but also in the cerebrospinal fluid produced by the choroid plexus of the brain, and in retinal pigment epithelium. This protein was originally called prealbumin as it runs faster than albumin ([[1bm0]]) during SDS-PAGE <ref> Seibert FB, Nelson JW.

After discovering its binding and transport ability to thyroxine (T4), it was given the name of “thyroxine-binding prealbumin” (TBPA).
