Abstract

We have isolated a cDNA coding for the core protein of the large basement membrane heparan sulfate proteoglycan (HSPG) from a human fibrosarcoma cell (HT1080) library. The library was screened with a mouse cDNA probe and one clone obtained, with a 1.5-kb insert, was isolated and sequenced. The sequence contained an open reading frame coding for 507 amino acid residues with a 84% identity to the corresponding mouse sequence. This amino acid sequence contained several cysteine-rich internal repeats similar to those found in component chains of laminin. The HSPG cDNA clone was used to assign the gene (HSPG2) to the p36.1----p35 region of chromosome 1 using both somatic cell hybrid and in situ hybridization. In the study of the polymorphisms of the locus, a BamHI restriction fragment length polymorphism was identified in the gene. This polymorphism displayed bands of 23 and 12 kb with allele frequencies of 76 and 24%, respectively.
