Gene Information

human ... SIAT1(6480)

General description

β -galactoside α -2, 6-sialyltransferase 1 (ST6GAL1), is a type II membrane protein expressed mainly in the Golgi apparatus. It is encoded by the gene mapped to human chromosome 3q21-28.

Immunogen

The antiserum was produced against synthesized peptide derived from human ST6GAL1.

Immunogen Range: 171-220

Biochem/physiol Actions

β -galactoside α -2, 6-sialyltransferase 1 (ST6GAL1) plays a vital role in transferring sialic acid from cytidine-monophosphate (CMP)-sialic acid onto galactose-containing substrates. ST6GAL1 has an essential role in the regulation of pluripotency and differentiation in human pluripotent stem cells (hPSCs). The encoded protein functions as important regulator of cell survival in several cell death pathways. Overexpression of this enzyme is observed in various cancers, including colon, breast, and epithelial tumor types. Increased expression of ST6GAL1 might affect cell motility and invasion. ST6GAL1 promoter hypermethylation results in loss of ST6GAL1 expression, therefore ST6GAL1 is considered to have a tumor suppressive role of in human bladder carcinogenesis.
