TCP — Solanum tuberosum

Summary

PGSC0003DMG400012675, designated StTCP on potato chromosome 2, encodes an uncharacterized protein with chaperonin domains (TCP-1, Chaperonin_TCP-1_CS, Chap_CCT_zeta) and is annotated with ATP-dependent protein folding chaperone activity and ATP hydrolase activity. The gene is associated with protein folding and refolding, protein-peroxisome targeting, and responses to abscisic acid, zinc, and stress. It has been linked to regulation of cell growth, virus-induced PTGS, and NO storage. Localisation evidence links the product to the cytosol, nucleus, plastid, mitochondria, and the TriC/CCT complex. Trait associations include axillary bud size, selenium content, and sulfur content. Studies of the Arabidopsis relative PEX7 connect the family to peroxisome function and PTS2 protein import, while related genes in other species have been linked to floral organ size, leaf length, seed weight, fruit traits, cytokinin and auxin content, and cadmium tolerance.
