Abstract

Using the differential hybridization screening method between osteoblastic and fibroblastic cells, a cDNA clone coding for an osteoblast specific protein, named OSF-1, consisting of 168 amino acid residues including a possible 32 amino acid long leader sequence, was isolated from murine osteoblastic cell line MC3T3-E1. The OSF-1 gene was shown by Northern blotting analysis to be expressed in mouse calvarial osteoblast-enriched cells and in mouse brain tissues, but not in thymus, spleen, kidney, liver, lung, testis or heart. The human counterpart was also found in cDNA libraries from human osteosarcoma cell line MG63 and normal brain tissues. DNA sequence analysis revealed four amino acid sequence differences between the mouse and human, of which only one is located in the mature protein. This extremely high sequence conservation suggests that OSF-1 plays a fundamental role in bone and brain functions.
