  • Application notes
    Is unsuitable for Flow Cyt,ICC or IP.
  • Target

    • Function

      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.
    • Sequence similarities

      Belongs to the calycin superfamily. Lipocalin family.
