TCP — Daucus carota subsp. sativus

Summary

DCAR_025918, also known as DcTCP, encodes a T-complex protein 1 subunit zeta, a chaperonin with ATP-dependent protein folding chaperone activity and ATP hydrolase activity. This carrot gene on chromosome 7 is associated with protein folding and refolding, response to hormones, developmental processes, and response to zinc. It has been connected to protein-peroxisome targeting and PTS2 protein import into peroxisomes, as well as reduced peroxisomal defects, reduced sensitivity to IBA, and fewer lateral roots. The gene is linked to selenium and sulfur content. Its product localises to the cytosol, nucleus, plastid, mitochondria, and the TriC complex. Studies of related genes in other species connect the family to cadmium tolerance, nitric oxide production, and PTS1 protein import into peroxisomes, while sequence similarity links the family to traits including seed weight, fruit weight and colour, leaf size and shape, and chlorophyll content.
