CC   -!- FUNCTION: Potent agonist for both PKR1/PROKR1 and PKR2/PROKR2, and
CC       inducer of a potent and long-lasting hyperalgesia. Also potentiates
CC       capsaicin-induced TRPV1 current, when tested on DRG neurons. At
CC       subnanomolar concentrations, this protein both induces potent
CC       chemotaxis of macrophages and stimulates LPS-induced production of the
CC       pro-inflammatory cytokines IL-1 and IL-12. In vivo, potently stimulates
CC       the contraction of the guinea-pig gastrointestinal (GI) smooth muscle
CC       (nanomolar concentration). {ECO:0000250|UniProtKB:Q9PW66}.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Expressed by the skin glands.
CC   -!- SIMILARITY: Belongs to the AVIT (prokineticin) family. {ECO:0000305}.
