  • FunctionThyroid hormone-binding protein. Probably transports thyroxine from the bloodstream to the brain.
  • Tissue specificityDetected in serum and cerebrospinal fluid (at protein level). Highly expressed in choroid plexus epithelial cells. Detected in retina pigment epithelium and liver.
  • Involvement in diseaseDefects in TTR are the cause of amyloidosis transthyretin-related (AMYL-TTR) [MIM:105210]. A hereditary generalized amyloidosis due to transthyretin amyloid deposition. Protein fibrils can form in different tissues leading to amyloid polyneuropathies, amyloidotic cardiomyopathy, carpal tunnel syndrome, systemic senile amyloidosis. The disease includes leptomeningeal amyloidosis that is characterized by primary involvement of the central nervous system. Neuropathologic examination shows amyloid in the walls of leptomeningeal vessels, in pia arachnoid, and subpial deposits. Some patients also develop vitreous amyloid deposition that leads to visual impairment (oculoleptomeningeal amyloidosis). Clinical features include seizures, stroke-like episodes, dementia, psychomotor deterioration, variable amyloid deposition in the vitreous humor.
    Defects in TTR are a cause of hyperthyroxinemia dystransthyretinemic euthyroidal (HTDE) [MIM:145680]. It is a condition characterized by elevation of total and free thyroxine in healthy, euthyroid persons without detectable binding protein abnormalities.
    Defects in TTR are a cause of carpal tunnel syndrome type 1 (CTS1) [MIM:115430]. It is a condition characterized by entrapment of the median nerve within the carpal tunnel. Symptoms include burning pain and paresthesias involving the ventral surface of the hand and fingers which may radiate proximally. Impairment of sensation in the distribution of the median nerve and thenar muscle atrophy may occur. This condition may be associated with repetitive occupational trauma, wrist injuries, amyloid neuropathies, rheumatoid arthritis.
  • Sequence similaritiesBelongs to the transthyretin family.
  • DomainEach monomer has two 4-stranded beta sheets and the shape of a prolate ellipsoid. Antiparallel beta-sheet interactions link monomers into dimers. A short loop from each monomer forms the main dimer-dimer interaction. These two pairs of loops separate the opposed, convex beta-sheets of the dimers to form an internal channel.

  • Immunohistochemical analysis of 4% PFA in 0.1M PBS perfusion-fixed frozen murine neural tissue, labelling prealbumin with ab75815 at a dilution of 1/200 incubated for 24 hours at 4°C in 0.1M PBST with 10% donkey serum. Peermeablization was with 0.1M PBS with 3% Triton X. Blocking was with 10% serum incubated for 1 hour at 24°C. Secondary was a rabbit Alexa Fluor® 488 (green) conjugate at 1/1000. Counterstaining (red) was against GFAP with a 588 fluorescence conujugate.

Thank you for your inquiry.

Unfortunately, ab75815, ab92469, and ab133284 (2434-1, 2524-1, 3168-1) were not raised from a region between a.a. 105 - 115. I took a look at the rest of the prealbumin antibodies in our catalogue and sadly none we...
