GMPPA, Official Symbol GMPPAprovided by HGNC Official Full Name GDP-mannose pyrophosphorylase Aprovided by HGNC Primary source HGNC:HGNC:22923 See related Ensembl:ENSG00000144591 MIM:615495; AllianceGenome:HGNC:22923 Gene type protein coding RefSeq status REVIEWED Organism Homo sapiens Lineage Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo Also known as AAMR Summary This gene is thought to encode a GDP-mannose pyrophosphorylase. This enzyme catalyzes the reaction which converts mannose-1-phosphate and GTP to GDP-mannose which is involved in the production of N-linked oligosaccharides.
