Ligand for G-protein coupled receptor FPRL2
View Patent ↗The present invention relates to methods, reagents and kits for detecting of formyl peptide receptor like-2 (FPRL2) polypeptide activity in a sample and identifying agents which modulate polypeptide activity. It further relates to antibodies raised against FPRL2. It further relates to substances for preventing, treating and/or alleviating diseases or disorders characterized by dysregulation of FPRL2 polypeptide signalling.
1. An isolated heme binding protein (HBP) polypeptide consisting essentially of the amino acid sequence represented by SEQ ID NO:18 or SEQ ID NO:19, wherein said polypeptide specifically binds FPRL2 having the amino acid sequence represented by SEQ ID NO: 2.
2. The isolated HBP polypeptide of claim 1 , wherein the HBP polypeptide is detectably labeled.
3. The isolated HBP polypeptide of claim 2 , wherein the detectable label is a moiety selected from the group consisting of a radioisotope, a fluorophore, a quencher of fluorescence, an enzyme, and an affinity tag.
4. A composition comprising the polypeptide of claim 1 .
