CYP — Daucus carota subsp. sativus

Summary

DCAR_011597 (symbol CYP, preferred name DcCYP26-2) on carrot chromosome 3 encodes a cyclophilin-type peptidyl-prolyl cis-trans isomerase (PPIase) with cyclosporin A binding activity. The gene is associated with protein folding and proline isomerization, as well as regulation of protein refolding. It has been linked to responses to abscisic acid, salt, and mannitol, and to activation of the salinity response. Associations also include carotenoid anabolism. The encoded protein localizes to the chloroplast stroma, mitochondria, cytosol, plasmalemma, cytoplasm, and nucleus. Studies of related genes in other species link the cyclophilin-type PPIase family to protein content, photochemical quenching, and salt tolerance traits.
