mammals amongst the Theriiformes (the sister taxon to Yinotheria.) Theria includes the eutherians that includes the placental mammals and the metatherians that includes the marsupials. More specifically, the InterPro profiles link the two components of Fel d 1 to the rodent androgen-binding protein (ABP; not to be confused with the human SHBG), a salivary pheromone. A homolog of Fel d 1 protein is also present in the venom of the slow loris (Primate: Nycticebus). Slow lorises are one of only a few venomous mammals and the only known venomous primate. They possess a dual-composite venom of saliva and brachial gland exudate (BGE). The BGE possesses a protein resembling Fel d 1, which may affect host species as an allergen as a constituent of the venom. It possess a communicative function.
