[[https://www.uniprot.org/uniprot/RET4_HUMAN RET4_HUMAN]] Defects in RBP4 are a cause of retinol-binding protein deficiency (RBP deficiency) [MIM:[https://omim.org/entry/180250 180250]]. This condition causes night vision problems. It produces a typical 'fundus xerophthalmicus', featuring a progressed atrophy of the retinal pigment epithelium.

== Publication Abstract from PubMed ==
Human serum retinol binding protein (RBP) in complex with retinol has been crystallographically refined to an R-factor of 18.1% with 2A resolution data. The protein topology results in an anti-parallel beta-barrel that encapsulates the retinol ligand. A detailed description of the protein and the binding site is provided. Our structural work has helped to define a family of proteins, many of which are carrier proteins for smaller ligand molecules. We describe the structural basis for the conservation of sequence within the family.
