Prokineticin receptor 2 (PKR₂), is a G protein-coupled receptor encoded by the PROKR2 gene in humans.

Function

Prokineticins are secreted proteins that can promote angiogenesis and induce strong gastrointestinal smooth muscle contraction. The protein encoded by this gene is an integral membrane protein and G protein-coupled receptor for prokineticins. The encoded protein is similar in sequence to GPR73, another G protein-coupled receptor for prokineticins.

Mutations in the PROKR2 (also known as KAL3) gene have been implicated in hypogonadotropic hypogonadism and gynecomastia.
