Human Gene FABP4 (ENST00000256104.5) from GENCODE V44
  Description: Homo sapiens fatty acid binding protein 4 (FABP4), mRNA. (from RefSeq NM_001442)
RefSeq Summary (NM_001442): FABP4 encodes the fatty acid binding protein found in adipocytes. Fatty acid binding proteins are a family of small, highly conserved, cytoplasmic proteins that bind long-chain fatty acids and other hydrophobic ligands. It is thought that FABPs roles include fatty acid uptake, transport, and metabolism. [provided by RefSeq, Jul 2008].

  ID: FABP4_HUMAN
DESCRIPTION: RecName: Full=Fatty acid-binding protein, adipocyte; AltName: Full=Adipocyte lipid-binding protein; Short=ALBP; AltName: Full=Adipocyte-type fatty acid-binding protein; Short=A-FABP; Short=AFABP; AltName: Full=Fatty acid-binding protein 4;
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 (By similarity).
SUBUNIT: Homodimer. Interacts with PPARG (By similarity). Monomer.
SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Note=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 (By similarity).
DOMAIN: Forms a beta-barrel structure that accommodates hydrophobic ligands in its interior.
SIMILARITY: Belongs to the calycin superfamily. Fatty-acid binding protein (FABP) family.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
