Thus, this study demonstrates that AML-1B can increase gene expression of an osteoblast-specific gene through its binding to an osteoblast-specific cis-acting element and presents evidence that OSF2 is a member of the PEBP2 alpha/AML-1 family of transcription factors .
 protein: transcription factors; DNA: osteoblast-specific gene; protein: PEBP2 alpha/AML-1 family; DNA: osteoblast-specific cis-acting element; protein: OSF2; protein: AML-1B
