Identity of the RNase MRP– and RNase P–associated Th/To autoantigen

Abstract excerpt

OBJECTIVE: To characterize the molecular identity of the Th/To autoantigen, which is targeted by autoantibodies in scleroderma and which is associated with the human RNase MRP and RNase P ribonucleoprotein complexes. METHODS: Proteins immunoprecipitated by anti-Th/To+ patient antisera from biotinylated total HeLa cell extracts were analyzed by immunoblotting. The association of autoantigenic proteins with the...
