CPN60 — Pisum sativum

Summary

PSAT7G128880 (CPN60, PsCPNA2) encodes a chaperonin 60 alpha subunit (Cpn60/GroEL family) that is an ATP-dependent protein folding chaperone with ATP binding activity. The gene is associated with protein folding, refolding, import, targeting, and structural organization, as well as responses to light intensity. It is linked to seed maturation, seed germination, and embryo development ending in seed dormancy. The protein localizes to mitochondria and cytoplasm. Studies of related genes in other species connect the CPN60 family to plant embryo development traits, including embryo lethality and developmental arrest at the globular stage, as well as photochemical quenching. In garden pea, the gene is located on chromosome 7LG7.
