Web22 mrt. 2024 · The soluble carrier hormone binding protein (HBP) plays an important role in the growth of human and other animals. HBP can also selectively and non-covalently interact with hormone. Therefore, accurate identification of HBP is an important prerequisite for understanding its biological functions and molecular mechanisms. Webity assays reveal that the hormone binding sites are distinct from the peptide/protein binding sites. PDI has one estradiol binding site with modest affinity (2.1 6 0.5 mM). There are two binding sites with comparable affin-ity for T 3 (4.3 6 1.4 mM). One of these overlaps the estra-diol site, whereas the other binds the hydrophobic probe, bis-ANS. gareth owen new boy https://prodenpex.com
