MAT1A: Proteins and Enzymes

MAT1A and MAT2A are catalytic subunits of methionine adenosyltransferase (MAT), which catalyzes the formation of S-adenosyltransferase for methionine catabolism. Inactivation of MAT1A has been linked to liver disease. In addition, in certain liver cancers, expression of MAT1A is replaced by expression of MAT1B. Overexpression of MAT2A has also been...
