    摘要: The translation product of the growth arrest-specific gene 6 (gas6) has been identified as an activator of the Mer receptor protein tyrosine kinase. The invention accordingly provides methods of activating Mer receptor in cells expressing it by exposing them to exogenous gas6 polypeptides. Also provided are methods of enhancing the growth, differentiation, or survival of such cells using gas6 polypeptides.

    摘要: An isolated TGF-.beta. supergene family (TSF) receptor polypeptide is provided. This polypeptide preferably is an inhibin/activin receptor polypeptide and has at least 75% sequence identity with the mature human inhibin/activin receptor sequence. Also provided is a method for purifying TGF-.beta. supergene family members such as inhibin or activin using the polypeptide, and a method for screening for compounds with TGF-.beta. supergene family member activity by contacting the compound with the polypeptide and detecting if binding has occurred and the compound is active.
