==Solution structure of the twelfth cysteine-rich ligand-binding repeat in rat megalin==
-
Megalin, an approx. 600 kDa transmembrane glycoprotein that acts as, multi-ligand transporter, is a member of the low density lipoprotein, receptor gene family. Several cysteine-rich repeats, each consisting of, about 40 residues, are responsible for the multispecific binding of, ligands. The solution structure of the twelfth cysteine-rich, ligand-binding repeat with class A motif found in megalin features two, short beta-strands and two helical turns, yielding the typical fold with a, I-III, II-V and IV-VI disulfide bridge connectivity pattern and a calcium, coordination site at the C-terminal end. The resulting differences in, electrostatic surface potential compared to other ligand-binding modules, of this gene family, however, may be responsible for the functional, divergence.
