| abstractText | Thrombospondins are a family of extracellular, adhesive proteins that are widely expressed in vertebrates. Five distinct gene products, designated thrombospondin-1 through -4 and cartilage oligomeric matrix protein (COMP), have been identified. With the exception of thrombospondin-4, the structure and location of thrombospondin genes have been determined in the human and/or mouse genomes. In this study, the structure and location of the murine thrombospondin-4 gene and the location of the human thrombospondin-4 gene are reported. The murine thrombospondin-4 gene is approximately 4.5 kb in length and includes 22 exons. Interspecific backcross analysis of progeny derived from matings of (C57BL/6J x Mus spretus)F(1) x C57BL/6J mice indicates that the thrombospondin-4 gene is tightly linked to the Dhfr locus on murine Chromosome (Chr) 13. The human gene maps to Chr 5 in band q13 by in situ hybridization to human metaphase chromosomes. The thrombospondin-4 promoter is similar to promoters of some housekeeping, growth control, and other thrombospondin genes in that it contains multiple GC box sequences and lacks a CAAT box. The presence of multiple E-box sequence motifs is consistent with thrombospondin-4 expression in muscle and bone tissue. |
