Protein attributes

Sequence length	510 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Responsible for synthesis of murine T-lymphocyte CT antigen. Can add to the low molecular weight acceptor 3'-sialyl-N-acetyllactosamine, to form a non-reducing terminal tetrasaccharide structure.
Catalytic activity	UDP-N-acetyl-D-galactosamine + (N-acetylneuraminyl)-D-galactosyl-D-R = UDP + N-acetyl-D-galactosaminyl-(N-acetylneuraminyl)-D-galactosyl-R.
Pathway	Protein modification; protein glycosylation.
Subcellular location	Golgi apparatus membrane; Single-pass type II membrane protein.
Sequence similarities	Belongs to the glycosyltransferase 2 family.
