This Recombinant Mouse Transthyretin (Ttr) was produced in mammalian cell, where the gene sequence encoding mouse Ttr (21-147aa) was expressed with the C-terminal 10xHis tag. The purity of this Ttr protein was greater than 95% by SDS-PAGE. The activity was validated.

Transthyretin (TTR), also known as vitamin A-binding protein, prealbumin, and thyroid-binding prealbumin, is mainly secreted by the liver and distributed in plasma and cerebrospinal fluid. The main function of TTR in the body is to participate in the transport of thyroxine and retinol, and maintain the normal levels of retinol, thyroxine and retinol-binding protein in the body. TTR can sensitively reflect the nutritional status and pathological changes of the body. It has been proved that TTR is related to various diseases of the human body, such as familial thyroid amyloidosis and diabetes. And many studies have also shown that the expression of TTR in the plasma and tumor cells of patients with various tumors is abnormal, so TTR is considered as one of the candidate tumor markers.

Target Background

Thyroid hormone-binding protein. Probably transports thyroxine from the bloodstream to the brain.
Gene References into Functions
  1. A C57BL/6 mouse line carrying the transthyretin (TTR) Gly83Arg gene mutation was successfully established. This strain of mice can be used for the study of hereditary vitreous amyloidosis. PMID: 29360446
  2. Results indicate that TTR stability is important for its recently described functions in assisting Abeta transport at the BBB and at the liver and also in regulating LRP1 levels and activity. TTR stabilization can serve as an avenue to increase both Abeta elimination and LRP1 levels, which in turn will further participate in Abeta clearance. PMID: 28570028

  10. Native transthyretin inhibits all preeclampsia-like features in the humanized mouse model. PMID: 24035612
  11. Transthyretin silencing (TTRkd) significantly reduced myogenin expression. PMID: 23717457
  12. Amyloid fibrils formed by a mutant form of TTR, A25T, activate microglia, leading to the secretion of tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and nitric oxide. PMID: 24008733
  13. Hsf-1 affects podocyte markers NPHS1, NPHS2 and WT1 in a transgenic mouse model of TTRVal30Met-related amyloidosis. PMID: 23829269
  14. Fibroblasts endocytose and degrade transthyretin aggregates in transthyretin-related amyloidosis. PMID: 23817086
  15. Increased degradation of 14-3-3zeta in lysosomes in the absence of TTR, increasing autophagy. PMID: 23523922
  16. our data demonstrate that the increased expression of Ttr in ob/ob mice does not cause (but rather attenuates) their phenotypic abnormalities. PMID: 22849972
  17. TTR has an important and nonredundant role in influencing the development of several organs. PMID: 23092911
  18. Results suggest that TTR expressed in pancreatic alpha cells may play important roles in glucose homeostasis via regulating the expression of glucagon. PMID: 23108050
  19. TTR binds to Grp78 at the plasma membrane, is internalized into the beta-cell via a clathrin-dependent pathway, and that this internalization is necessary for the effects of TTR on beta-cell function. PMID: 22183612
  20. the expression of transthyretin and protein kinase Cgamma were increased in the prefrontal cortex but not in the hippocampus of naltrexone-treated mice PMID: 21111029
