Preferred Label : Molybdenum Cofactor Biosynthesis Protein 1;

NCIt synonyms : EC 4.1.99.22; EC 4.6.1.17; MOCS1; Cell Migration-Inducing Gene 11 Protein; Molybdenum Cofactor Synthesis-Step 1 Protein A-B;

NCIt definition : Molybdenum cofactor biosynthesis protein 1 (636 aa, 70 kDa) is encoded by the human MOCS1 gene. This protein plays a role in the conversion of 5'-GTP to cyclic pyranopterin monophosphate (cPMP).;

NCIt note : Several MOCS1A and MOCS1B isoforms may be produced due to alternative splicing or independent translation of a bicistronic transcript. The MOCS1B isoform (also called MOCS1B Type-II) is the canonical form according to UniProt.; The GTP 3',8-cyclase (EC 4.1.99.22; molybdenum cofactor biosynthesis protein A) and cyclic pyranopterin monophosphate synthase (EC 4.6.1.17; molybdenum cofactor biosynthesis protein C) activities of molybdenum cofactor biosynthesis protein 1 are likely dependent on the formation of complexes containing both isoform MOCS1A and isoform MOCS1B.
