Conjugate Avi-tag Biotinylated
E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Storage Condition Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Functions as retinol transporter. Accepts all-trans retinol from the extracellular retinol-binding protein RBP4, facilitates retinol transport across the cell membrane, and then transfers retinol to the cytoplasmic retinol-binding protein RBP1. Retinol uptake is enhanced by LRAT, an enzyme that converts retinol to all-trans retinyl esters, the storage forms of vitamin A. Contributes to the activation of a signaling cascade that depends on retinol transport and LRAT-dependent generation of retinol metabolites that then trigger activation of JAK2 and its target STAT5, and ultimately increase the expression of SOCS3 and inhibit cellular responses to insulin. Important for the homeostasis of vitamin A and its derivatives, such as retinoic acid. STRA6-mediated transport is particularly important in the eye, and under conditions of dietary vitamin A deficiency. Does not transport retinoic acid.
Gene References into Functions
  1. Mutations in retinoic acid 6 gene (STRA6) have been reported in clinically diagnosed patients with MWS. Here we presented a case with MWS, who has characteristic findings of the syndrome as well as dextrocardia as an undescribed feature, and bilateral streak gonads which was described only in one patient previously. Molecular analysis showed a homozygous exonic missense mutation in the STRA6 gene. PMID: 30204971
  2. The knockdown of STRA6 slightly enhanced nodule formation at the late stage of osteoblast differentiation, and overexpression of STRA6 in ST2 cells enhanced adipocyte differentiation. PMID: 29067460
  3. these data demonstrate a key role of STRA6 and RBP4 in the maintenance of colon cancer self-renewal and that this pathway is an important link through which consumption of HFD contributes to colon carcinogenesis. PMID: 28689994
  4. this study suggested that a role of STRA6 polymorphism could also be of value in predicting the risk of type 2 diabetes mellitus(T2DM) while RARRES2 polymorphism could not predict the risk of T2DM PMID: 27446956
  5. A novel mutation in two Hmong families broadens the range of STRA6-related malformations to include contractures and camptodactyly. PMID: 26373900
  6. These data establish that holo-RBP and its receptor STRA6 are potent oncogenes and suggest that the pathway is a novel target for therapy of some human cancers. PMID: 25237067
  7. Evidence for the existence of a transmembrane pore, analogous to the pore of ion channels, in STRA6. PMID: 24223695
  8. STRA6 has a role for regulating retinoid homeostasis and in helping to program signaling that drives proliferation and differentiation of human skin cells PMID: 24284421
  9. Stra6, a retinoic acid-responsive gene, participates in p53-induced apoptosis after DNA damage. PMID: 23449393
  10. Analysis of FRAS1 and STRA6 mutations in the same family with eye anomalies. PMID: 22283518
  11. Findings suggest that heterozygosity for the STRA6 gene mutation may be associated with ocular abnormalities. PMID: 22686418
  12. 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
  13. STRA6 orchestrates a multicomponent machinery that couples vitamin A homeostasis and metabolism to activation of a signaling cascade and that, in turn, STRA6 signaling regulates the cellular uptake of the vitamin. PMID: 22665496
  14. STRA6 mutations can cause isolated eye malformations in addition to the congenital anomalies observed in MWS. PMID: 21901792
  15. SNPs in STRA6, gene coding the cell surface receptor for RBP4, were significantly associated with type 2 diabetes and further genetic and functional studies are required to understand and ascertain its role in the manifestation of type 2 diabetes. PMID: 20625434
  16. Mutations in STRA6 cause a broad spectrum of malformations including anophthalmia, congenital heart defects, diaphragmatic hernia, alveolar capillary dysplasia, lung hypoplasia, and mental retardation PMID: 17273977
  17. Matthew-Wood syndrome is caused by truncating mutations in the retinol-binding protein receptor gene STRA6. PMID: 17503335
  18. In fibroboasts, STRA6 transports retinol bidirectionally in an RBP4 dependent manner. PMID: 18316031
  19. study identifies an essential functional domain in STRA6 and a human polymorphism in this domain that leads to reduced vitamin A uptake activity PMID: 18387951
  20. This study explores the association of STRA6 and SKI genes in a cohort of subjects with anophthalmia and microphthalmia. PMID: 19112531
  21. Two novel STRA6 mutations in a patient with anophthalamia and diaphragmatic eventration are reported. PMID: 19213032
  22. Six novel mutations were identified in STRA6. PMID: 19309693
