St6gal1
Function
Transfers sialic acid from CMP-sialic acid to galactose-containing acceptor substrates.
Pathway
Protein modification; protein glycosylation.
Post-translational modifications
The soluble form derives from the membrane form by proteolytic processing.
N-glycosylated.
Sequence Similarities
Belongs to the glycosyltransferase 29 family.
