Description
Description: Formiminotransferase Cyclodeaminase Human Recombinant (also called liver cytosol type 1) produced in SF9, is a glycosylated, polypeptide chain having a molecular mass of 59,749 Dalton.The FTCD is expressed with a -6xHis tag and purified by proprietary chromatographic techniques.
Introduction: Formiminotransferase cyclodeaminase is an enzyme which catalyzes the conversion of formiminoglutamateand tetrahydrofolateinto formiminotetrahydrofolateand glutamate.Formiminotransferase cyclodeaminase, a bifunctional enzyme of tetrahydrofolate synthesis, is the target antigen of anti-LC1 (liver cytosol antigen type 1) autoantibodies. Presence of LC1 autoantibodies is a marker for type 2 autoimmune hepatitis (for which anti-LKM 1/cytochrome P450 2D6 autoantibodies are a further marker).Serum LC1 autoantibody concentrations appear to fluctuate in parallel with aminotransferase levels, a particularly intriguing observation that suggests a possible role of LC1 autoreactivity in the pathogenic mechanism leading to hepatocyte injury
