Plasma retinol binding protein 4
Plasma retinol-binding protein
Plasma retinol-binding protein(1-176)
Retinol binding protein 4
Retinol binding protein 4 interstitial
Retinol binding protein 4 plasma
Delivers retinol from the liver stores to the peripheral tissues. In plasma, the RBP-retinol complex interacts with transthyretin, this prevents its loss by filtration through the kidney glomeruli.
Involvement in disease
Defects in RBP4 are a cause of retinol-binding protein deficiency (RBP deficiency) [MIM:180250]. This condition causes night vision problems. It produces a typical 'fundus xerophthalmicus', featuring a progressed atrophy of the retinal pigment epithelium.
Belongs to the calycin superfamily. Lipocalin family.
