RBP3: Proteins and Enzymes

RBP3, also known as Retinol-binding protein 3, is a secreted 135 kDa 1247 amino acid protein. RBP3 plays a critical role in the visual process by transporting retinoids between the retinal pigment epithelium and the photoreceptors. RBP3 is currently being studied in relationship to retinitis, retinoblastoma, Behcet's disease, diphtheria, night blindness and proliferative vitreoretinopathy. RBP3 is linked to the g1phase, cell cycle, induction of apoptosis, visual cycle I and cell cycle arrest pathways where it interacts with MCPH1, TFDP1, TFDP2, NOTCH1 and RB1.
