CC   -!- FUNCTION: IRBP shuttles 11-cis and all trans retinoids between the
CC       retinol isomerase in the pigment epithelium and the visual pigments in
CC       the photoreceptor cells of the retina.
CC   -!- SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular
CC       matrix, interphotoreceptor matrix. Note=Interphotoreceptor matrix that
CC       permeates the space between the retina and the contiguous layer of
CC       pigment epithelium cells.
