Target

  • Function

    Lipid transport protein in adipocytes. Binds both long chain fatty acids and retinoic acid. Delivers long-chain fatty acids and retinoic acid to their cognate receptors in the nucleus.
  • 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. Depending on the nature of the ligand, a conformation change exposes a nuclear localization motif and the protein is transported into the nucleus. Subject to constitutive nuclear export.
  • Target information above from: UniProt accession P15090 The UniProt Consortium
    The Universal Protein Resource (UniProt) in 2010
    Nucleic Acids Res. 38:D142-D148 (2010) .
