Belongs to the CorA metal ion transporter (MIT) (TC 1.A.35.5) family. Could be the product of a pseudogene. In strain cv. Columbia, a naturally occurring frameshift at position 277 results in a truncated MRS2-8 protein lacking the two transmembrane regions, which are conserved features of the family. A complete sequence for MRS2-8 can be found in strain cv. Landsberg erecta (AC P0CZ21).
