Two retinoic acid-binding proteins, a high molecular weight one (90-100 kDa) (peak A) and CRABP (peak B), were obtained on gel filtration column chromatography of extracts of limb buds of chick embryos. The presence of a retinoic acid receptor (RAR) (45 kDa) and the absence of chick-CRABP type II (16.2 kDa) in the peak A fractions suggested that the 45 kDa RAR forms a homo- or hetero-dimeric structure (90-100 kDa) with other RARs or other nuclear proteins, but not with chick-CRABP type II, in the limb buds of chick embryos. We also demonstrated that there were no significant differences in the amount of RAR in the anterior, middle and posterior parts of limb buds (stages 23-25).

D018168	Receptors, Retinoic Acid	Proteins in the nucleus or cytoplasm that specifically bind RETINOIC ACID or RETINOL and trigger changes in the behavior of cells. Retinoic acid receptors, like steroid receptors, are ligand-activated transcription regulators. Several types have been recognized.
