Carbohydrate sulfotransferase 12 (CHST12) is a member of the sulfotransferase family, which catalyzes the transfer of sulfate groups to carbohydrate moieties, particularly during the biosynthesis of sulfated glycosaminoglycans (GAGs). This enzyme is primarily involved in the sulfation of chondroitin sulfate, a critical component of the extracellular matrix (ECM), playing roles in cell adhesion, signaling, and tissue development. CHST12 specifically mediates the transfer of sulfate to the C-4 position of the N-acetylgalactosamine residue in chondroitin, forming chondroitin 4-sulfate (C4S), which influences ECM structure and interactions with growth factors or receptors.
The recombinant human CHST12 protein is engineered for in vitro studies to elucidate its enzymatic mechanisms, substrate specificity, and regulatory functions. Produced via heterologous expression systems (e.g., E. coli or mammalian cells), it enables biochemical assays, structural analysis, and drug discovery research. Dysregulation of CHST12 has been implicated in pathological conditions, including cancers, where altered chondroitin sulfate sulfation patterns may promote tumor progression, metastasis, or immune evasion. Additionally, mutations in CHST12 are linked to skeletal and connective tissue disorders, underscoring its importance in maintaining tissue integrity. Studying recombinant CHST12 aids in exploring therapeutic strategies targeting sulfation pathways or ECM remodeling in diseases. Its structure-function relationships, including conserved sulfotransferase domains and substrate-binding regions, remain key research focuses to unravel its biological and clinical significance.
