Target

  • Function
    Transports retinoic acid to the nucleus. Regulates the access of retinoic acid to the nuclear retinoic acid receptors.
  • Sequence similarities
    Belongs to the calycin superfamily. Fatty-acid binding protein (FABP) family.
  • Domain
    Forms a beta-barrel structure that accommodates hydrophobic ligands in its interior.
  • Cellular localization
    Cytoplasm. Nucleus. Upon ligand binding, a conformation change exposes a nuclear localization motif and the protein is transported into the nucleus.
