Abstract

Human N-acetylglucosaminyltransferase V (GnT-V, EC 2.4.1.155) cDNA was isolated from a human fetal liver cDNA library. Oligonucleotide primers for polymerase chain reaction were designed according to the amino acid sequence of human GnT-V. Screening for the cDNA was carried out by plaque hybridization using PCR products of about 500 bp. Human GnT-V has 741 amino acids and six putative N-glycosylation sites. The homology to rat GnT-V is 88% at the nucleotide level and is 97% at the amino acid level, and there is one amino acid insertion. Using the cDNA clones as probe, five overlapping genomic clones have been isolated from a human phagemid DNA library. The GnT-V gene has been mapped to chromosome 2q21 using fluorescence in situ hybridization.
