CYP — Camelina sativa

Summary

CsCYP21-2 (CSA09G068030) on Camelina sativa chromosome 9 encodes a cyclophilin-type peptidyl-prolyl cis-trans isomerase (PPIase) with cyclosporin A binding and cis-trans proline isomerase activity. The gene is associated with protein folding, regulation of protein refolding, detoxification, and responses to abscisic acid, salt, and mannitol, as well as activation of salinity response. Its product localises to multiple cellular compartments including the cytosol, nucleus, chloroplast stroma, Golgi complex, endosome, and plasmalemma. CsCYP21-2 is associated with seed germination and seedling growth. Studies of the related Arabidopsis CYP21-2 connect the family to water stress tolerance, and sequence similarity links the family to traits including germination rate, chlorophyll content, root length, and seedling and seed growth and development.
