Outer dense fibers are structures unique to the sperm tail. No definite function for these fibers has been found, but they may play a role in motility and provide elastic recoil. Their composition had been described before, but only two of the fiber proteins, Odf1 and Odf2, are cloned. We cloned Odf2 by virtue of its functional and specific interaction with Odf1, which, we show, is mediated by a leucine zipper....
