This protein stains blue-green in Masson's trichrome stain, and this protein appears red in the presence of both Verhoeff's stain and a Van Gieson counterstain.
This protein stains blue-green in Masson's trichrome stain, and this protein appears red in the presence of both Verhoeff's stain and a Van Gieson counterstain. Defects in the PLOD1 gene result in the kyphoscoliosis version of a condition in which this protein's assembly is disrupted. The enzyme lysyl oxidase catalyzes the formation of aldehydes from lysines in the final step of this protein's synthesis. (*) Glycine residues compose roughly one-third of this protein, which alongside fibronectin is a common ligand for integrin proteins. Enzymes in the synthesis of this compound require a Vitamin C cofactor, and this protein typically assumes a compact, triple helical structure. For 10 points, name this fibrous protein that composes most of the ECM and many connective tissues.
