The thyroid microsomal antigen (MSA) in autoimmune thyroid disease is a protein of approximately 107 kD. We screened a human thyroid cDNA library constructed in the expression vector lambda gt11 with anti-107-kD monoclonal antibodies. Of five clones obtained, the recombinant beta-galactosidase fusion protein from one clone (PM-5) was confirmed to react with the monoclonal antiserum. The complementary DNA (cDNA) insert from PM-5 (0.8 kb) was used as a probe on Northern blot analysis to estimate the size of the mRNA coding for the MSA. The 2.9-kb messenger RNA (mRNA) species observed was the same size as that coding for human thyroid peroxidase (TPO). The probe did not bind to human liver mRNA, indicating the thyroid-specific nature of the PM-5-related mRNA. The nucleotide sequence of PM-5 (842 bp) was determined and consisted of a single open reading frame. Comparison of the nucleotide sequence of PM-5 with that presently available for pig TPO indicates 84% homology. In conclusion, a cDNA clone representing part of the microsomal antigen has been isolated. Sequence homology with porcine TPO, as well as identity in the size of the mRNA species for both the microsomal antigen and TPO, indicate that the microsomal antigen is, at least in part, TPO.Images
