Is likely involved in the transport of fructoselysine and psicoselysine to the cytoplasm, where they are degraded. N(6)-(D-fructosyl)-L-lysine(in) = N(6)-(D-fructosyl)-L-lysine(out) N(6)-(D-psicosyl)-L-lysine(in) = N(6)-(D-psicosyl)-L-lysine(out) Carbohydrate metabolism; fructoselysine degradation. Belongs to the amino acid-polyamine-organocation (APC) superfamily.
