21D7 — Daucus carota subsp. sativus

Summary

DCAR_022816 (symbol 21D7, also known as DcHAP15) on carrot chromosome 6 encodes a nuclear antigen 21D7 protein that possesses tRNA-adenosine deaminase, ATP hydrolase, and protein-binding activities, and is associated with enzyme modulator activity. The gene is associated with tRNA wobble adenosine-to-inosine editing, tRNA modification, mRNA nuclear export, DNA replication, and regulation of protein breakdown. It is linked to meristem growth and structural organization, phyllome and root cap development, male and female gamete generation, and responses to hydrogen peroxide, viruses, and misfolded proteins. The protein localizes to the proteasome regulatory particle, plasmodesmata, cell wall, cytosol, mitochondria, and plasma membrane. Associations include zinc and herbicide sensitivity, oxidative stress resistance, disease tolerance, cell cycle traits, embryo development, and root and inflorescence morphology. Related genes in other species are linked to telomere maintenance and DNA damage response.
