Definition

ChEBI: O-(N-acetyl-alpha-D-galactosaminyl)-L-serine is a non-proteinogenic L-amino acid that is N-acetyl-alpha-D-galactosamine linked via an alpha glycosidic bond to the O at position 3 of L-serine. It has a role as a tumour antigen. It is a L-serine derivative and a non-proteinogenic L-alpha-amino acid.

General Description

Tn antigen?is a truncated O-glycan, that is commonly noticed in colorectal cancer (CRC). It is usually expressed at high levels in cancer cells. Tn antigen is small in size and simple in structure. It has a non-physiological glycan structure in humans, hence it may be identified as foreign by the immune system.

Biochem/physiol Actions

Tn antigen stimulates colorectal cancer metastasis through the activation of epithelial-mesenchymal transition, mediated by H-Ras. It acts as a precursor to several significant complex O-glycans. Subpopulations of blood cells in all lineages carrying the Tn antigen results in a hematological disorder called Tn syndrome.
