Mat2b Gene Summary [Mouse]
Predicted to enable enzyme binding activity and methionine adenosyltransferase regulator activity. Predicted to be involved in S-adenosylmethionine biosynthetic process. Located in mitochondrion. Is expressed in several structures, including brain; early conceptus; genitourinary system; respiratory system; and sensory organ. Orthologous to human MAT2B (methionine adenosyltransferase 2 non-catalytic beta subunit). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Mat2b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
