Nucleic acids encoding DCRS5
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. An isolated or recombinant polynucleotide comprising a sequence having at least 95% sequence identity with SEQ ID NO:1, wherein the polynucleotide encodes a polypeptide which. alonci with IL-12Rβ1, is able to form a functional receptor complex for p40/IL-B30.
2. The polynucleotide of claim 1 comprising SEQ ID NO:1.
3. An expression vector comprising the polynucleotide of claim 1 .
4. An isolated host cell comprising the expression vector of claim 3 .
5. The isolated host cell of claim 4 , wherein the host cell is:
a) a mammalian cell;
b) an insect cell;
c) a bacterial cell; or
d) yeast cell.
6. A method of producing an antigenic polypeptide of SEQ ID NO:2 comprising:
a) culturing the host cell of claim 4 under conditions suitable for expression of the polypeptide; and
b) isolating or purifying the polypeptide.
7. A kit comprising the nucleic acid of claim 1 , and:
a) a compartment for containing said nucleic acid of claim 1 ;
b) a nucleic acid encoding human IL12Rβ1 polypeptide; or
c) instructions for use of said nucleic acid of claim 1 .
8. A polynucleotide encoding a polypeptide comprising the sequence of residues 1-606 of SEQ ID NO:2.
9. The polynucleotide of claim 8 encoding a polypeptide comprising the sequence of SEQ ID NO:2.
