Background

BMP‑8, also known as osteogenic protein 2 (OP‑2), was first isolated from a hippocampal library in a screen to identify relatives of BMP‑7/OP‑1 (1). BMPs are a family of structurally and functionally related proteins and represent a subfamily of the transforming growth factor beta (TGF‑ beta ) superfamily. BMPs are involved in a wide range of processes including embryogenesis, tissue morphogenesis, cell differentiation and migration, and tumorigenesis. Cellular responses to BMPs are mediated by hetero‑oligomeric complexes of type I and type II serine/threonine kinase receptors (2‑4). BMP‑8a and BMP‑8b, produced from separate genes, share 98% amino acid sequence identity in human but only 74% in mouse within the mature regions. Mouse BMP‑8a is synthesized as a 399 aa precursor protein that is cleaved between Arg260 and Ala261 to release the C‑terminal mature protein. Mature mouse BMP‑8a shares 90% aa sequence identity with mature human BMP‑8a and ‑8b. BMP‑8a is expressed during pregnancy in the deciduum and trophoblast cells, by inner root sheath cells of developing hair follicles, and by the epididymis and spermatids (5‑7). In the mouse it cooperates with BMP‑7 in the maintenance of spermatogenesis but is not required for the initiation of spermatogenesis (7, 8). BMP‑8b, in contrast, is required for both the initiation and maintenance of spermatogenesis (9). BMP‑8a is induced during osteoblast differentiation at the onset of mineralization and during the osteogenic phase of bone repair in osteoblasts and osteocytes (10‑12). BMP‑8a/b is also highly expressed in osteosarcomas (13).
