Post-GPI attachment to proteins factor 4 and similar proteins; This family includes post-GPI attachment to proteins factor 4 (PGAP4), also known as post-GPI attachment to proteins GalNAc transferase 4 or transmembrane protein 246 (TMEM246). PGAP4 has been shown to be a Golgi-resident GPI-GalNAc transferase. Many eukaryotic proteins are anchored to the cell surface through glycolipid glycosylphosphatidylinositol (GPI). GPIs have a conserved core but exhibit diverse N-acetylgalactosamine (GalNAc) modifications. PGAP4 knockout cells lose GPI-GalNAc structures. PGAP4 is most likely involved in the initial steps of GPI-GalNAc biosynthesis. In contrast to other Golgi glycotransferases, it contains three transmembrane domains. This family also includes uncharacterized fungal proteins with similarity to PGAP4.

 96-218 1.34e-42

N-Acetylglucosaminyltransferase-IV (GnT-IV) conserved region; The complex-type of oligosaccharides are synthesized through elongation by glycosyltransferases after trimming of the precursor oligosaccharides transferred to proteins in the endoplasmic reticulum. N-Acetylglucosaminyltransferases (GnTs) take part in the formation of branches in the biosynthesis of complex-type sugar chains. In vertebrates, six GnTs, designated as GnT-I to -VI, which catalyze the transfer of GlcNAc to the core mannose residues of Asn-linked sugar chains, have been identified. GnT-IV (EC:2.4.1.145) catalyzes the transfer of GlcNAc from UDP-GlcNAc to the GlcNAc1-2Man1-3 arm of core oligosaccharide [Gn2(22)core oligosaccharide] and forms GlcNAc1-4(GlcNAc1-2)Man1-3 structure on the core oligosaccharide (Gn3(2,4,2)core oligosaccharide). In some members the conserved region occupies all but the very for N-terminal, where there is a signal sequence on all members. For other members the conserved region does not occupy the entire protein but is still to the N-terminus of the protein.
