Functional comparison of the Hoxa 4, Hoxa 10, and Hoxa 11 homeoboxes.

Abstract excerpt

A number of models attempt to explain the functional relationships of Hox genes. The functional equivalence model states that mammalian Hox-encoded proteins are largely functionally equivalent, and that Hox quantity is more important than Hox quality. In this report, we describe the results of two homeobox swaps. In one case, the homeobox of Hoxa 11 was replaced with that of the very closely related Hoxa 10....
