title: The E-Box motif, recognized by tissue-specific nuclear factor(s), is important for BMP-4 gene expression in osteogenic cells.
abstract: We analyzed the promoter activity of mouse BMP-4 gene in three different types of cell lines and demonstrated that position -786 to -691 of the 5'-flanking region of exon I plays a critical role for regulation of tissue specific expression of mouse BMP-4 gene in cells of an osteogenic lineage. By use of site-directed mutagenesis, we have established that the E-box, CATCTG, located within this 5'-flanking region, is essential for tissue-specific transcriptional activation of mouse BMP-4 gene and demonstrated that an osteogenic lineage-specific novel transcriptional factor(s) recognizes this E-box.
