CRABP2, Cellular retinoic acid-binding protein 2, Cellular retinoic acid-binding protein II, CRABP-II
This gene encodes a member of the retinoic acid (RA, a form of vitamin A) binding protein family and lipocalin/cytosolic fatty-acid binding protein family. The protein is a cytosol-to-nuclear shuttling protein, which facilitates RA binding to its cognate receptor complex and transfer to the nucleus. It is involved in the retinoid signaling pathway, and is associated with increased circulating low-density lipoprotein cholesterol. Alternatively spliced transcript variants encoding the same protein have been found for this gene.[provided by RefSeq, Dec 2010],domain:Forms a beta-barrel structure that accommodates hydrophobic ligands in its interior.,function:Transports retinoic acid to the nucleus. Regulates the access of retinoic acid to the nuclear retinoic acid receptors.,induction:By retinoic acid.,similarity:Belongs to the calycin superfamily. Fatty-acid binding protein (FABP) family.,subcellular location:Upon ligand binding, a conformation change exposes a nuclear localization motif and the protein is transported into the nucleus.,subunit:Interacts with RXR and RARA (By similarity). Interacts with importin alpha.,
