Onager Asiatic cheetahs, and possibly bears, though they may have mostly preyed only on onager foals. In India, mugger crocodiles can be great threats to onagers during migratory river crossings. Currently, the biggest predator for onagers are gray wolves. About 23% of prey proportion of gray wolves were on the Asian wild ass. However, like most equids, they are known to have antipredator protection. Groups of stallions cooperate and try to chase off predators. If threatened, onagers defend themselves and violently kick at the incoming predator. The greatest threat facing the onager is poaching for meat and hides, and in some
Fibronectin type III domain Fibronectin type III domain The Fibronectin type III domain is an evolutionary conserved protein domain that is widely found in animal proteins. The fibronectin protein in which this domain was first identified contains 16 copies of this domain. The domain is about 100 amino acids long and possesses a beta sandwich structure. Of the three fibronectin-type domains, type III is the only one without disulfide bonding present. Fibronectin domains are found in a wide variety of extracellular proteins. They are widely distributed in animal species, but also found sporadically in yeast, plant and bacterial proteins. ABI3BP; ANKFN1; ASTN2; AXL; BOC;
