| Tissue Specificity | Detected in serum and cerebrospinal fluid (at protein level). Highly expressed in choroid plexus epithelial cells. Detected in retina pigment epithelium and liver. |
| Post Translational Modifications | Not glycosylated under normal conditions. Following unfolding, caused for example by variant AMYLD1 'Gly-38', the cryptic Asn-118 site is exposed and glycosylated by STT3B-containing OST complex, leading to its degradation by the ER-associated degradation (ERAD) pathway. Sulfonation of the reactive cysteine Cys-30 enhances the stability of the native conformation of TTR, avoiding misassembly of the protein leading to amyloid formation. |
| Function | Thyroid hormone-binding protein. Probably transports thyroxine from the bloodstream to the brain. |
