UniProt:Q7LFX5 CHST15
The addition of GalNAc to the terminal glucuronate residue forms chondroitin
A glucuronate moiety is added to chondroitin
GalNAc is added to chondroitin
Chondroitin can be sulfated on position 4 of GalNAc by CHST9, 11, 12 and 13
Chondroitin 4-sulfate (C4S) can be further sulfated on position 6 by CHST15
Chondroitin can be sulfated on position 6 of GalNAc by CHST3,7
CSPG is secreted
