OX NCBI_TaxID=10090; RN [1] RP NUCLEOTIDE SEQUENCE. RC TISSUE=Brain, and Liver; RX MEDLINE=94363344; PubMed=8081843; DOI=10.1016/S0968-0896(00)82111-2; RA Hamamoto T., Kawasaki M., Kurosawa N., Nakaoka T., Lee Y.-C., RA Tsuji S.; RT "Two step single primer mediated polymerase chain reaction. RT Application to cloning of putative mouse, beta-galactoside alpha 2,6- RT sialyltransferase cDNA."; RL Bioorg. Med. Chem. 1:141-145(1993). CC -!- FUNCTION: Transfers sialic acid from the donor of substrate CMP- CC sialic acid to galactose containing acceptor substrates. CC -!- CATALYTIC ACTIVITY: CMP-N-acetylneuraminate + beta-D-galactosyl- CC 1,4-N-acetyl-beta-D-glucosamine = CMP + alpha-N-acetylneuraminyl- CC 2,6-beta-D-galactosyl-1,4-N-acetyl-beta-D-glucosamine. CC -!- PATHWAY: Glycosylation. CC -!- SUBCELLULAR LOCATION: Type II membrane protein. Membrane-bound CC form in trans cisternae of Golgi. Soluble form in body fluids. CC -!- PTM: The soluble form derives from the membrane form by CC proteolytic processing. CC -!- SIMILARITY: Belongs to the glycosyltransferase 29 family.
