[[http://www.uniprot.org/uniprot/OCP_SYNY3 OCP_SYNY3]] Acts as a photo-protectant. Essential for inhibiting white and blue-green light non-photochemical quenching (NPQ). Binding carotenoids improves OCP's intrinsic photoprotectant activity by broadening its absorption spectrum and facilitating the dissipation of absorbed energy.<ref>PMID:16531492</ref>
