CYP — Camelina sativa

Summary

CsMTERF20 (CYP, CSA15G047190) on Camelina sativa chromosome 15 encodes a protein with a cyclophilin-type PPIase domain and an MTERF domain, conferring cis-trans proline isomerase activity and double-stranded DNA binding, and it binds cyclosporin A. The gene is associated with protein folding and refolding regulation, detoxification, chloroplast organization, and responses to salt, mannitol, and abscisic acid. Its product localizes to the chloroplast stroma, cytosol, nucleus, and plasmalemma. Related genes in other species link the MTERF20 family to mitochondrial transcription termination and, via sequence similarity, to photochemical quenching and arsenic concentration traits, though these associations are not yet established in Camelina sativa.
