FAM155A

B1AL88

Glycosyltransferase required for the biosynthesis ofheparan-sulfate. The EXT1/EXT2 complex possesses substantiallyhigher glycosyltransferase activity than EXT1 or EXT2 alone.Appears to be a tumor suppressor. Required for the exosomalrelease of SDCBP, CD63 and syndecan (PubMed:22660413).{ECO:0000269|PubMed:11518722, ECO:0000269|PubMed:22660413}.

check buttonRetention analysis result of each fusion partner protein across 39 protein features of UniProt such as six molecule processing features, 13 region features, four site features, six amino acid modification features, two natural variation features, five experimental info features, and 3 secondary structure features. Here, because of limited space for viewing, we only show the protein feature retention information belong to the 13 regional features. All retention annotation result can be downloaded at
