    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.

  • 功能：
    Capable of catalyzing the interconversion of testosterone and androstenedione, as well as estradiol and estrone. Also has 20-alpha-HSD activity. Uses NADH while EDH17B3 uses NADPH.

    8. SNP variants in the 17beta-HSD2 and 17beta-HSD7 genes and 17beta-HSD7 copy number is associated with increased estradiol levels in breast cancer tissues. PMID: 24560990
    9. overexpression of 17beta-HSD2 in sebocytes significantly increased the androstenedione production and markedly decreased the amounts of testosterone and dihydrotestosterone PMID: 24938708

    28. 17beta-HSD type 2 was expressed in 20% of breast cancer specimens. decrease in 17beta-HSD type 2 expressions in breast cancer may play a role in the development &/or progression of cancer by modifying the intratumoral levels of estrogens & androgens. PMID: 18996480
    29. preference of 17betaHSD2 for E2 oxidation strongly resists alteration by genetic & metabolic means. Findings suggest additional structural features, beyond lack of a specific Arg residue, disfavor NADPH binding & thus support E2 oxidation by 17betaHSD2 PMID: 19556422
