Prokineticin GPCR Family Subtypes and Products

What Are Prokineticin Receptors?

Prokineticin receptors are a family of G protein-coupled receptors (GPCRs) comprised of two receptor subtypes: PKR1 and PKR2. Prokineticin receptors play a role in the regulation of a variety of biological processes such as circadian rhythms, GI motility, angiogenesis, hematopoiesis, and neurogenesis. Research, however, is still being done on the biology of this newly discovered family of receptors.

PK1

PK2

Prokineticin receptor 1 (PK1 or GPR73) is a receptor for the cysteine-rich secreted peptides prokineticin 1 and 2. RT-PCR detected GPR73 expression in the brain, testis, small intestine, ovary, thyroid, pituitary and salivary gland.

Prokineticin receptor 2 (PK2 or GPR73L1) is a receptor for the cysteine-rich secreted peptides prokineticin 1 and 2. RT-PCR detected PK2 expression in the brain, testis, small intestine, ovary, thyroid, pituitary, and salivary gland.
