The chondroitin polymerase complex transfers one GlcA moiety from UDP-GlcA to the CS chain. It consists of any two subunits from the chondroitin sulfate synthases CHSY1, CHSY3, CHPF2, CHPF (reviewed in Mikami & Kitagawa, 2013). They possess both beta-1,3-glucuronic acid and beta-1,4-N-acetylgalactosamine transferase activity (Kitagawa et al. 2001, Yada et al. 2003, Yada et al. 2003b). Defects in CHSY1 cause Temtamy preaxial brachydactyly syndrome (TPBS) (MIM:605282) (Tian et al. 2010, Li et al. 2010).
