Mouse CX3C chemokine polypeptides
View Patent ↗Nucleic acids encoding a new family of chemokines, the CX3C family, from a mammal, reagents related thereto, including specific antibodies, and purified proteins are described. Methods of using said reagents and related diagnostic kits are also provided.
1. An isolated polypeptide wherein said polypeptide a) chemoattracts peripheral blood monocytes or T-cells, b) consists of an amino acid sequence comprising at least 95% amino acid sequence identity to the amino acid sequence set forth in SEQ ID NO 8; and c) comprises a chemokine domain identical to residues 25 to 100 of the amino acid sequence set forth in SEQ ID NO: 8.
2. The polypeptide of claim 1 , which comprises the amino acid sequence set forth in SEQ ID NO: 8.
3. A composition comprising the polypeptide of claim 1 and a carrier.
4. The composition of claim 3 wherein the carrier is water, saline, or buffer.
5. The polypeptide fused to a heterologous protein.
6. The polypeptide of claim 5 wherein the heterologous protein is a FLAG peptide.
7. A method for producing an isolated polypeptide wherein said polypeptide a) chemoattracts peripheral blood monocytes or T-cells, b) consists of an amino acid sequence comprising at least 95% amino acid sequence identity to the amino acid sequence set forth in SEQ ID NO: 8, and c) comprises a chemokine domain identical to residues 25 to 100 of the amino acid sequence set forth in SEQ ID NO: 8; comprising introducing a vector comprising a polynucleotide encoding said polypeptide into an isolated host cell and culturing said host cell.
8. The method of claim 7 wherein the polypeptide comprises the amino acid sequence set forth in SEQ ID NO: 8.
