CYP — Cucumis sativus

Summary

CsCYP, encoded by the cucumber gene CSA_5G128260 on chromosome 5, is a cyclophilin-type peptidylprolyl isomerase (PPIase) with cis-trans proline isomerase activity, and is also annotated for cyclosporin A binding, salicylic acid binding, peroxidase activity, and U5/U2 snRNA binding. The gene is associated with diverse biological processes including protein proline isomerization, chaperone-mediated protein complex assembly, alternative mRNA splicing, basipetal auxin transport, and responses to light intensity, sulfate starvation, and arsenic. It has been linked to traits such as variegated leaf, starch grain synthesis, respiration rate, photosynthetic rate, sucrose content, root hair length, herbicide sensitivity, and temperature stress response. Localization evidence connects CsCYP to the Golgi stack, thylakoid lumen, secretory vesicle, and proteasome. Studies of related genes in other species link the family to hydrotropism, phototropism, cold stress tolerance, embryo patterning, and drought response.
