Short chain dehydrogenase/reductase family 23E member 1
FunctionNon-catalytic regulatory subunit of S-adenosylmethionine synthetase 2 (MAT2A), an enzyme that catalyzes the formation of S-adenosylmethionine from methionine and ATP. Regulates the activity of S-adenosylmethionine synthetase 2 by changing its kinetic properties, rendering the enzyme more susceptible to S-adenosylmethionine inhibition.
Tissue specificityWidely expressed.
PathwayAmino-acid biosynthesis; S-adenosyl-L-methionine biosynthesis; S-adenosyl-L-methionine from L-methionine: step 1/1.
Sequence similaritiesBelongs to the dTDP-4-dehydrorhamnose reductase family. MAT2B subfamily.
