the aba-1 allergen of ascaris lumbricoides: sequence polymorphism, stage and tissue-specific expression, lipid binding function, and protein biophysical properties. | the aba-1 protein of ascaris lumbricoides (of humans) and ascaris suum (of pigs) is abundant in the pseudocoelomic fluid of the parasites and also appears to be released by the tissue-parasitic larvae and the adult stages. the genes encoding the polyprotein precursor of aba-1 (aba-1) were found to be arranged similarly in the two taxa, comprising tandemly repeating units encoding a large polyprotein which is cleaved to yield polypeptides of approximately 15 kda which fall into 2 distinct classes ... | 2000 | 10726282 |
