PPI — Cicer arietinum

Summary

CYC, the chickpea (Cicer arietinum) gene on chromosome 6, encodes a cyclophilin-type peptidyl-prolyl cis-trans isomerase (PPIase) with cis-trans proline isomerase activity, cyclosporin A binding, and structural constituent of the ribosome. It is associated with diverse biological processes including protein folding and refolding, regulation of protein phosphorylation, translation, signal transduction, and responses to salt, mannitol, light stimulus, and bacterial molecules. CYC is linked to defence response to bacteria, negative regulation of the hypersensitive response, and hypersensitive response-programmed cell death, as well as brassinosteroid-mediated signalling, de-etiolation, and blue and red/far-red light phototransduction. The gene product localises to the cytosol, membrane, chloroplast stroma, apoplast, mitochondria, mitochondrial ribosomal small subunit complex, stress granule, and plasma membrane. Related genes in other species are linked to innate immunity, basal defence, disease resistance, and stomatal aperture regulation.
