A fatty acid-binding protein and a protein disulphide isomerase-related protein expressed in urochordate gonad cytosol
Despite the evolutionary-tree data suggesting that gene duplication leading to the divergence of the three branches which heart, liver and intestinal fatty acid-binding proteins belong to must have occurred before the vertebrate/invertebrate split, only the heart fatty acid-binding protein has been...
