Function
Protein sialyltransferase specifically expressed in goblet cells that plays a key role in intestinal host-commensal homeostasis (PubMed:35303419). Conjugates sialic acid with an alpha-2-6 linkage to N-acetylgalactosamine (GalNAc) glycan chains linked to serine or threonine in glycoproteins (PubMed:16319059, PubMed:35303419). Catalyzes the formation of the sialyl-Tn (S-Tn) antigen, an antigen found in intestinal goblet cells, as well as ulcerative colitis (UC) and various cancers (PubMed:16319059, PubMed:35303419). Protein sialylation in globlet cells is essential for mucus integrity and is required to protect the intestinal mucus against excessive bacterial proteolytic degradation (PubMed:35303419).

Supplementary info

- Activity summary
ST6GalNAc I also known as ST6 N-acetylgalactosaminide alpha-26-sialyltransferase 1 plays an important mechanical role in glycosylation processes. It adds sialic acid to the terminal position of N-acetylgalactosamine on glycoproteins. The enzyme has a molecular weight of around 55 kDa. Expression of ST6GalNAc I is found predominantly in the Golgi apparatus where glycosylation occurs. It is expressed in tissues such as the liver heart and brain though expression levels can vary.
- Biological function summary
ST6GalNAc I is involved in the regulation of cell-to-cell interactions and immune responses. It is not known to be a part of larger enzyme complexes but operates independently adding sialic acid residues that can modify the properties and functions of glycoproteins on the cell surface. These modifications can influence cell signaling migration and adhesion through their effects on the cell glycocalyx.
- Pathways
ST6GalNAc I plays a role in the sialylation pathway which affects processes like cellular communication and protein stability. The enzyme's activity influences the O-glycan biosynthesis pathway. It works alongside other proteins such as ST3Gal I and ST6Gal I to fine-tune the sialylation states of glycoconjugates. This tuning can significantly impact interactions at the cell surface therefore influencing downstream signaling events.
- Associated diseases and disorders
ST6GalNAc I has a link to cancer and autoimmune disorders. Abnormal expression or activity of ST6GalNAc I can alter glycosylation patterns contributing to the progression of colon cancer by influencing tumor cell metastasis and immune cell evasion. Changes in its activity also have associations with autoimmune conditions where they may disrupt normal immune cell recognition and response. The target's modulation affects other proteins like MUC1 often implicated in cancer and immune-related anomalies.
