statistical analysis of the amino acid and mrna sequences of human l-fabp , rat l-fabp , rat intestinal ( i- ) fabp , and mouse 422 protein indicates that the human and rat l-fabps are highly homologous and that l-fabp and i-fabp diverged a long time ago ( approximately 650-690 million years ago ) , although they are more closely related to each other than either of them is to 422 protein .
