CRALBP Recombinant Rabbit Monoclonal Antibody [PSH0-74]

Retinaldehyde-binding protein 1 (RLBP1) also known as cellular retinaldehyde-binding protein (CRALBP) is a 36-kD water-soluble protein that in humans is encoded by the RLBP1 gene. The cellular retinaldehyde-binding protein transports 11-cis-retinal (also known as 11-cis-retinaldehyde) as its physiological ligands. It plays a critical role as an 11-cis-retinal acceptor which facilitates the enzymatic isomerization of all 11-trans-retinal to 11-cis-retinal, in the isomerization of the rod and cones of the visual cycle. CRALBP is not just found in retina and retinal pigment epithelial cells, but also expressed in other cell types. It is majorly found in the iris, cornea, ciliary epithelium, Muller cells, the pineal gland and oligodendrocytes of the optic nerve and brain. This protein is also found in other tissues than the aforementioned ones, however its function in cells not related to the eyes are not yet known.
