Protein Name:
Mannose-1-phosphate guanylyltransferase catalytic subunit beta
|
UniprotKB/SwissProt ID: Q9Y5P6 (Q9Y5P6)
Gene Name:
GMPPB
Organism: Homo sapiens (Human)
Function: Catalytic subunit of the GMPPA-GMPPB mannose-1-phosphate guanylyltransferase complex (PubMed:33986552). Catalyzes the formation of GDP-mannose, an essential precursor of glycan moieties of glycoproteins and glycolipids (PubMed:33986552). Can catalyze the reverse reaction in vitro (PubMed:33986552). Together with GMPPA regulates GDP-alpha-D-mannose levels (PubMed:33986552)
