A number of ELISA Kits are available that target KAL3, an alias of the protein, prokineticin receptor 2. The human protein, encoded by the gene PROKR2, is a member of the G-protein coupled receptor 1 family. The protein's cellular localization is indicated to be membrane-associated. Additional synonyms or past names for this protein may include: GPR73L1, GPR73b, GPRg2, HH3, KAL3, PKR2, dJ680N4.3. Homology is conserved in other species, such as Mouse, Rat, Frog, Chicken.
