CPN10 — Cicer arietinum

Summary

LOC101490851 (CaCPN10) on chickpea chromosome 7 encodes a chaperonin protein belonging to the Cpn20/GroES family, with annotated molecular functions including superoxide dismutase copper carrier activity, magnesium chelatase activity, histidine kinase binding, and protein folding chaperone activity. The gene is associated with protein heterotetramerization, nitrogen fixation, downregulation of abscisic acid-mediated signaling, protein folding, and response to cold. It localizes to the magnesium chelatase complex, plastid stroma, chloroplast membranes, thylakoid, and mitochondria. CaCPN10 is associated with water stress response, chloroplast development, stomatal closure and opening, seed growth, root morphology, and drought tolerance. Associations also include abscisic acid sensitivity and signaling, chlorophyll biosynthesis, retrograde signaling, copper homeostasis, and reactive oxygen species production. Related genes in other species connect the family to chloroplast protein folding, ozone tolerance, ABA perception, and iron deficiency tolerance.
