CYC — Pisum sativum

Summary

PSAT5G003080 (CYC, PsCYC) on garden pea chromosome 5LG3 encodes a cyclophilin-type peptidyl-prolyl cis-trans isomerase (EC 5.2.1.8) with cis-trans proline isomerase activity, cyclosporin A binding, protein binding, and structural constituent of ribosome functions. The gene is associated with diverse biological processes including protein folding, regulation of protein phosphorylation and refolding, blue light signaling, red/far-red light phototransduction, de-etiolation, response to stress and bacterial molecules, starch anabolism, gluconeogenesis, lipid oxidation, lipolysis, NO storage, and negative regulation of the hypersensitive response. It has been linked to traits such as flour particle size, ash and protein content, stomatal opening, bacterial disease response, and disease tolerance. Localization evidence connects the product to the chloroplast stroma, mitochondria, mitochondrial ribosomal small subunit complex, cytosol, plasma membrane, apoplast, and stress granules. Studies of related genes in other species link the family to plant immune response, basal defense, and stomatal aperture regulation.
