Three genes encoding membrane-secreted proteins have been successfully isolated from osteoblast-like cell lines by using a method for specifically cloning membrane-secreted proteins. As the result of subsequent analysis on one of these genes, it has been found out that the protein encoded by this gene is a novel receptor protein which has an extracellular region alone binds to cell membranes via a GPI anchor and carries therein a cysteine-rich repetitive region conserved in the TNF receptor super family. It has been also found out that when this protein is largely expressed in an osteoblast-like cell line, the proliferation of the cells are suppressed the cells are , morphologically …

Why it's free to use
- Filed April 1, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 1, 2018.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
