Mannose-1-Phosphate Guanylyltransferase Regulatory Subunit Alpha

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** Mannose-1-phosphate guanylyltransferase regulatory subunit alpha (420 aa, ~46 kDa) is encoded by the human GMPPA gene. This protein plays a role in the biosynthesis of GDP-mannose from GTP and mannose-1-phosphate.

**Synonyms:** - GDP-Mannose Pyrophosphorylase A - GMPP-Alpha - GMPPA - GTP-Mannose-1-Phosphate Guanylyltransferase Alpha
