IRBP (1-20), human is the 1-20 fragment of interphotoreceptor retinoid binding protein (IRBP).This peptide is a 1 to 20 amino acid fragment of the interphotoreceptor retinoid binding protein (IRBP). IRBP is a 140-kDa glycolipoprotein residing in the interphotoreceptor matrix between the neural retina and the retinal pigment epithelium.

G-1749 does not alter the monomer-dimer equilibrium of IRE, stimulates the RNase activity of unphosphorylated IRE1 and inhibits IRE1-3P, and significantly increases the RNase activity of IRE1-KR-0P.
