'CRALBP' also known as cellular retinaldehyde-binding protein is a protein involved in the visual cycle. It weighs approximately 36 kDa. Expressed mainly in the retina CRALBP is found in retinal pigment epithelial (RPE) cells and Muller glial cells. It binds to retinoids which are critical for proper vision functioning. CRALBP also goes by the synonyms such as 'BSA b 2' which is used in specific contexts related to its role in retinal metabolism.
Biological function summary

The protein aids in the effective conversion of all-trans-retinal to 11-cis-retinal an important step in the visual cycle. It acts as a chaperone that stabilizes retinoid intermediates facilitating their transport between various retinal cell types. CRALBP forms part of a complex with retinoid isomerohydrolase and 11-cis-retinol dehydrogenase enhancing its binding and transport function. This ensures smooth retinoid flux necessary for regenerating the visual pigment rhodopsin.

Pathways

CRALBP is integral to two main pathways; the retinoid cycle in cones and the rhodopsin regeneration pathway in rods. In these pathways it interacts with proteins such as RPE65 and 11-cis-retinol dehydrogenase ensuring efficient retinoid transfer and isomerization. This important involvement supports the regeneration of visual pigments necessary for photoreceptor cell function under various lighting conditions.

CRALBP associates with retina-related conditions notably congenital stationary night blindness (CSNB) and retinitis pigmentosa (RP). Mutations affecting CRALBP can alter retinoid transport and contribute to these disorders. Additionally CRALBP dysfunction links to other proteins like RPE65 and RDH5 which can also play roles in the pathogenesis of these visual impairments. Understanding these relationships helps in developing targeted treatments for retinoid-related visual disorders.

Target data

Soluble retinoid carrier essential the proper function of both rod and cone photoreceptors. Participates in the regeneration of active 11-cis-retinol and 11-cis-retinaldehyde, from the inactive 11-trans products of the rhodopsin photocycle and in the de novo synthesis of these retinoids from 11-trans metabolic precursors. The cycling of retinoids between photoreceptor and adjacent pigment epithelium cells is known as the 'visual cycle'.
