Persian onager found in desert steppes. Their largest population is found in Khar Turan National Park. The Persian onager is listed as endangered by IUCN Red List, as it is close to extinction. Currently, poaching for meat and hides, competition with livestock, and drought are the greatest threats to this species. Asiatic wild asses are highly and legally protected; hunting them is forbidden. The European Endangered Species Programme reserved for European Association of Zoos and Aquaria is helping save the Persian onager from extinction, by breeding them in captivity and reintroducing them to their former ranges, including in new locations once inhabited
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;
