Rbp3
Function
IRBP shuttles 11-cis and all trans retinoids between the retinol isomerase in the pigment epithelium and the visual pigments in the photoreceptor cells of the retina.
Sequence Similarities
Belongs to the peptidase S41A family.
Tissue Specificity
Expressed in the photosensitive tissues; retina and pineal gland.
Cellular localization
- Secreted
- Extracellular space
- Extracellular matrix
- Interphotoreceptor matrix
- Interphotoreceptor matrix that permeates the space between the retina and the contiguous layer of pigment epithelium cells.
Alternative names
Retinol-binding protein 3, Interphotoreceptor retinoid-binding protein, Interstitial retinol-binding protein, IRBP, Rbp3
