產品描述：

This Mouse Rbp4 recombinant protein was produced in mammalian cell, where the gene sequence encoding mouse Rbp4 (19-201aa.) was expressed with the C-terminal hFc tag. The purity of this Rbp4 protein was was greater than 94% by SDS-PAGE. Its activity was measured by its binding ability in a functional ELISA.
Retinol Binding Protein 4 (RBP4) is the carrier of retinol in the blood. It belongs to the lipocalin family and contains a 21 kD protein with a retinol binding site. RBP4 is the most important extracellular transporter, responsible for binding and transporting retinol in the blood. Adipose, kidney, testis, brain and digestive tract tissues can all synthesize and secrete RBP4. But under normal physiological conditions the main source of this protein is the liver. Many studies have found that RBP4 plays an important role in obesity, insulin resistance, metabolic syndrome, hypertension and atherosclerosis, and is expected to provide important clues for the pathogenesis and therapeutic targets of related diseases.

靶點詳情

功能：

Retinol-binding protein that mediates retinol transport in blood plasma. Delivers retinol from the liver stores to the peripheral tissues. Transfers the bound all-trans retinol to STRA6, that then facilitates retinol transport across the cell membrane.
基因功能參考文獻：
1. RBP4 is involved in all-trans retinoic acid-induced cleft palate. PMID: 28849085
2. RBP4-induced inflammation is largely mediated by TLR4. PMID: 28400700
3. New insights into ghrelin cell physiology, and given the known functions of RBP4 and TTR, support an emerging role for the ghrelin cell in blood glucose handling and metabolism. PMID: 23840311
4. Retinal degeneration in RBP4-Tg mice is RBP4-dependent and light-independent. PMID: 28813718
5. Rbp4-deficient mice accumulated retinol in the liver but it was undetectable in the serum, indicating an inverse relation between serum and liver retinol levels. RBP4 is critical for the mobilization of retinol from hepatic storage pools, and such mobilization is necessary for ocular development and visual function. PMID: 26974396
6. Hepatocytes Are the Principal Source of Circulating RBP4 in Mice PMID: 27797907
7. RBP4 may be a critical modulator promoting the vicious cycle of insulin resistance and heart failure by activating TLR4/MyD88-mediated inflammatory pathways. Potentially, lowering RBP4 might break the vicious cycle and improve both insulin resistance and cardiac hypertrophy. PMID: 27100622
8. Data (including data from studies in knockout mice) suggest that Rbp4 (plasma retinol-binding protein 4) is critical for antigen presentation and activation of CD4-positive T-lymphocyte in development of insulin resistance in mice obese due to high-fat diet. PMID: 26936962
9. A novel mechanism for circadian regulation of RBP4, but also a critical role of RBP4, acting as a hepatokine in the regulation of glucose metabolism by the circadian clock. PMID: 26564180
10. Elevated serum RBP4 raises BP. PMID: 25911613
11. These data show that decreasing circulating TTR levels or altering TTR-RBP4 binding could be a potential therapeutic approach for the treatment of type 2 diabetes. PMID: 25524914
12. findings suggest that RBP4 impaired in vivo adipogenesis, partly through the repression of the insulin pathway PMID: 24590924
13. The data implicate the involvement of chondrocytic Rbp4 in bone growth, particularly in the formation of the secondary ossification center of the limb. PMID: 23224267
14. STRA6 in tissues other than the eye appears to be the coupling of circulating holo-RBP levels to cell signaling, in turn regulating key processes such as insulin response. PMID: 23839944
15. expression of RBPR2 in liver and fat suggests a possible role in mediating established metabolic actions of RBP4 in those tissues PMID: 23105095
16. TTR blocks the ability of holo-retinol-binding protein to associate with STRA6 and thereby effectively suppresses both STRA6-mediated retinol uptake and STRA6-initiated cell signaling. PMID: 22826435
17. Suggest that RBP4 may be involved in the dyslipidemia associated with polycystic ovary syndrome in nonobese adolescents and that there may be an independent relationship between RBP4 and triglycerides but not between RBP4 and insulin resistance. PMID: 22341881
18. RBP4 is not only an adipocytokine, but also a hepatic cytokine leading to metabolic syndrome, non-alcoholic fatty liver disease and type 2 diabetes. PMID: 21983273
19. results indicate that rimonabant may improve vascular function by modulating RBP4 along with pro-inflammatory cytokines PMID: 21585349
20. Basal and cyclic AMP-induced Rbp4 transcription is regulated by a multiprotein complex that is similar to ones that modulate expression of genes of steroid hormone biosynthesis. PMID: 19389484
21. RBP4 is an adipocyte-derived 'signal' that may contribute to the pathogenesis of type 2 diabetes PMID: 16034410
22. Lowering transthyretin(TTR) levels or interfering with RBP4-TTR binding may enhance insulin sensitivity in obesity and type 2 diabetes PMID: 18285525
23. These results reveal a selective effect of all-trans retinoic acid inhibiting RBP4 expression specifically in adipocytes. PMID: 18769064
24. Identification and characterization of a non-retinoid ligand for retinol-binding protein 4 which lowers serum retinol-binding protein 4 levels in vivo. PMID: 19147488
25. HMGA1 is an important modulator of RBP4 gene expression in vivo. PMID: 19460132
26. Although mice lacking HMGA1 are diabetic and express very low levels of the insulin receptor, they have increased insulin sensitivity. Changes in circulating Rbp4 might partly account for this paradox. [REVIEW] PMID: 19664187
