DCRS5 polypeptides
View Patent ↗Nucleic acids encoding mammalian, e.g., primate, receptors, purified receptor proteins and fragments thereof. Antibodies, both polyclonal and monoclonal, are also provided. Methods of using the compositions for both diagnostic and therapeutic utilities are described.
1. A substantially pure or recombinant polypeptide comprising a sequence having at least 95% sequence identity with SEQ ID NO:2, wherein the polypeptide, when combined along with IL-12Rβ1, is able to form a functional receptor complex for p40/IL-B30.
2. A substantially pure or recombinant polypeptide comprising a sequence having at least 98% sequence identity with SEQ ID NO:2, wherein the polypeptide, when combined along with IL-12Rβ1, is able to form a functional receptor complex for p40/IL-B30.
3. A heterodimeric composition comprising the polypeptide of claim 1 and human IL-12Rβ1.
4. A kit comprising the polypeptide of claim 1 and instructions for use.
5. The kit of claim 4 , wherein the kit also contains:
a) human IL-12Rβ1 polypeptide;
b) human p40;
c) human IL-B30; or
d) human IL-B30/p40 polypeptides.
6. The polypeptide of claim 1 comprising a sequence having fewer than 5 substitutions relative to the sequence of SEQ ID NO:2.
