General Information

General Information Comment Organism
malfunction CSS2 knockout mice are viable and fertile, exhibiting no overt morphological abnormalities or osteoarthritis, but their cartilage contains chondroitin sulfate chains with a shorter length and although at a similar number to wild-type. CSS2 knockout chondrocyte culture systems, together with siRNA of CSS1, reveal the presence of two CS chain species in length, suggesting two steps of CS chain polymerization; i.e., elongation from the linkage region up to Mr of about 10,00 and further extension Mus musculus
metabolism CSS1 and CSS2 differently contribute to chondroitin sulfate biosynthesis, mechanism of chondroitin sulfate biosynthesis, overview. CSS1 participates in both the chondroitin sulfate chain initiation and polymerization, and CSS2 participates in the polymerization, especially in further extension Mus musculus
additional information the enzyme occurs in a heterooligomer complex, chondroitin sulfate synthase-2 (CSS2)/chondroitin polymerizing factor Mus musculus
