Gene Gene information from NCBI Gene database.
Entrez ID 29925
Gene name GDP-mannose pyrophosphorylase B
Gene symbol GMPPB
Synonyms (NCBI Gene)
LGMDR19MDDGA14MDDGB14MDDGC14
Chromosome 3
Chromosome location 3p21.31
Summary This gene is thought to encode a GDP-mannose pyrophosphorylase. The encoded protein catalyzes the conversion of mannose-1-phosphate and GTP to GDP-mannose, a reaction involved in the production of N-linked oligosaccharides. Alternatively spliced transcrip
