Economy of Afghanistan that Afghanistan was nearing self-sufficiency in grain production. The availability of land suitable for grazing has traditionally made animal husbandry an important part of the economy. There are two main types of animal husbandry: sedentary, practiced by farmers who raise both animals and crops; and nomadic, practiced by animal herders known as Kuchis. Natural pastures cover some but are being overgrazed. The northern regions around Mazar-i-Sharif and Maymanah were the home range for about six million karakul sheep in the late 1990s. Most flocks move to the highlands in the summer to pastures in the north. Oxen are the primary
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;
