HD6 — Oryza sativa Indica Group

Summary

BGIOSGA011241 (HD6, also known as OiCK2ALPHA3) on chromosome 3 of Indica rice encodes a protein with a CK2_alpha domain and protein serine/threonine kinase activity, cyclin binding, RNA polymerase II CTD heptapeptide repeat kinase activity, and ATP binding. It is associated with cell cycle control, including G1/S and G2/M transitions, meiotic and mitotic cell cycle modulation, cell division, DNA damage response, signal transduction, regulation of gene expression, photoperiodism, inflorescence and flower development, and heading date and anthesis time. The product localises to the casein kinase II complex, nucleus, cytosol, cytoplasm, spindle, NRD complex, and CDK holoenzyme. Studies of related genes in other species link the family to additional kinase activities (EC 2.7.11.22 and 2.7.11.23).
