matrix and contains a variety of distinct domains, including three repeating subunits (types I,
II, and III) that share homology to an assortment of other proteins. Determination of THBS1
gene structure has revealed that the type I repeat modules are encoded by symmetrical
exons and that the heparin-binding domain is encoded by a single exon. To further elucidate
the higher level organization of THBS1, the gene was localized to the q11-qter region of …
