Abstract

Collagen IV, a key structural protein of basement membranes, is vital for the development and survival of multicellular life forms. Its maturation relies on specific post-translational O- glycosylation, primarily mediated by lysyl hydroxylase-3 (LH3) and other glycosyltransferases, which sculpt collagen by modifying the hydroxylysine residues with sugar moieties.
