IRBP (651-670) (human) (trifluoroacetate salt)

Interphotoreceptor retinoid-binding protein (651-670) (IRBP651-670) is a peptide fragment of IRBP, also known as retinoid-binding protein 3, which is involved in pigment regeneration by transporting retinol and retinal from photoreceptor cells to retinal pigment epithelium. IRBP651-670 has been used to induce autoimmune uveoretinitis in C57BL/6 mice, which bear the H-2b haplotype. Immunization with IRBP651-670 (300 µg/animal) increases ocular IL-1beta, IL-6, IL-17, TNF-alpha, and IFN-gamma levels, immune cell infiltration, and photoreceptor damage in mice.Formal Name: L-leucyl-L-alanyl-L-glutaminylglycyl-L-alanyl-L-tyrosyl-L-arginyl-L-threonyl-L-alanyl-L-valyl-L-alpha-aspartyl-L-leucyl-L-alpha-glutamyl-L-seryl-L-leucyl-L-alanyl-L-seryl-L-glutaminyl-L-leucyl-L-threonine, trifluoroacetate salt.
