| abstractText | Serglycin (SGC) is a Ser-Gly-repeat-containing protein, used as a proteoglycan core protein in the parietal yolk sac and in mast cells, where glycosaminoglycan side chains are attached to the serine residues of the repeat region. In this article, the structure of the gene SGC encoding mouse SGC is reported. The gene is divided into three exons, which are all contained within a region of approximately 13 kb. Nucleotide (nt) sequence analysis was carried out on a region of 1.2 kb upstream from the first exon. The region containing the two promoters (active in parietal yolk sac and in mast cells, respectively) was analyzed for the presence of recognition sites for known DNA-binding proteins. A number of sequences closely related to known recognition sites were found in both promoters, and one consensus octamer-binding site could be identified in the putative yolk-sac promoter. Multiple regions in the mouse genome hybridizing with DNA fragments covering the Ser-Gly repeat region have previously been described, and it has been suggested that these loci may represent other proteoglycan core proteins. Analysis of nt sequence was carried out on three out of the more than 15 of these regions present in the mouse genome. However, none of the clones analyzed was found to have any open reading frame in the region of cross-hybridization which possibly could code for a SGC protein. Instead, one of the clones was found to contain an exon encoding a highly basic protein, unrelated to SGC. Hence, no evidence was found for a multigene family of Ser-Gly-repeat-containing proteoglycan-encoding genes. |
