We describe here experiments to examine the role of cellular retinoic-acid-binding protein (CRABP) during the induction of limb duplication in the chick limb bud and regenerating axolotl limb by retinoids. A newly synthesised class of retinoic acid analogues have been used because among them, some have been specifically designed with the property of binding to the retinoic acid receptors, but not to CRABP. We can thus test whether binding to CRABP is an obligatory step during limb respecification. The binding of four of these compounds to chick limb bud and axolotl CRABP was tested in sucrose density gradient assays and then their potencies at inducing limb duplications tested. Two of the four compounds do not bind to limb CRABP and yet are able to induce limb duplications, suggesting that an interaction with CRABP is not an obligatory step in the process. However, the two compounds which do bind to CRABP are more potent than the two which do not, suggesting that an interaction with CRABP may, nevertheless, increase the potency of a retinoid.
