Product Background

ST3GAL4 gene expression is altered in different cancer types, including cervical cancer. Several mRNA transcripts have been reported for this gene. ST3GAL4 encodes for β‑galactosidase α‑2,3‑sialyltransferase 4, involved in the biosynthesis of the tumour antigens sLe(x) and sulfo‑sLe(x).
