« Hide More detailed introduction

Prokineticin receptors, PKR1 and PKR2 (provisional nomenclature as recommended by NC-IUPHAR [5]) respond to the cysteine-rich 81-86 amino-acid peptides prokineticin-1 (PROK1, Q9HC23) (also known as endocrine gland-derived vascular endothelial growth factor, mambakine) and prokineticin-2 (PROK2, Q9HC23) (protein Bv8 homologue). An orthologue of PROK1 from black mamba (Dendroaspis polylepis) venom, mamba intestinal toxin 1 (MIT1, [16]) is a potent, non-selective agonist at prokineticin receptors [10], while Bv8, an orthologue of PROK2 from amphibians (Bombina sp., [11]), is equipotent at recombinant PKR1 and PKR2 [12], and has high potency in macrophage chemotaxis assays, which are lost in PKR1-null mice.
