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. [provided by RefSeq, Jul 2008]. * **UniProt Summary**: May serve as a regulatory subunit and allow allosteric feedback inhibition of GMPPB by GDP-mannose. {ECO:0000269|PubMed:24035193}. |Hexapep| |NTP transf 3| |NTP transferase| |nucleotidyltransferase activity| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp347|Cyclosporin-A 0.8μM R07 exp347]]|-2.34| |[[:results:exp318|ABT-702 5μM R07 exp318]]|-1.77| |[[:results:exp155|UNC1999 2μM R03 exp155]]|2.09| No correlation found to any other genes in chemogenomics.
