| 摘要 |
<p>Novel receptor polypeptides, polynucleotides encoding the polypeptides, and related compositions and methods are disclosed. The polypeptides comprise an extracellular domain of a cell-surface receptor that is expressed in pancreas, small intestine, colon and thymus. The polypeptides may be used within methods for detecting ligands that promote the proliferation and/or differentiation of these organs.</p> |
