In this context, they play a role in the regulation of social behaviors, such as aggression, mating, pup-suckling, territory establishment and dominance. Acts as a kairomone, detected by the prey vomeronasal organ and inducing fear reactions in mice.

Belongs to the calycin superfamily. Lipocalin family.

Abundant in the urine of adult male rats but absent from that of females.
