Molybdenum cofactor biosynthesis protein 1 is a protein that in humans and other animals, fungi, and cellular slime molds, is encoded by the MOCS1 gene.^[5]^[6] ^[7] ^[8]

Both copies of this gene are defective in patients with molybdenum cofactor deficiency, type A.^[8]

Molybdenum cofactor biosynthesis is a conserved pathway leading to the biological activation of molybdenum. The protein encoded by this gene is involved in molybdopterin biosynthesis. (This gene was originally thought to produce a bicistronic mRNA with the potential to produce two proteins (MOCS1A and MOCS1B) from adjacent open reading frames. However, only the first open reading frame (MOCS1A) has been found to encode a protein from the putative bicistronic mRNA.) Two of the splice variants found for this gene express proteins (MOCS1A-MOCS1B) that result from a fusion between the two open reading frames.
