CPK29 — Sorghum bicolor

Summary

SORBI_3004G338000 (symbol CPK29, also known as SbPPCK1) on sorghum chromosome 4 encodes a protein kinase domain-containing protein with calcium-dependent protein serine/threonine kinase activity, calmodulin binding, calcium ion binding, ATP binding, and Ca2+/CaM-dependent kinase activity. It is associated with C4 photosynthesis, intracellular signal transduction, seed development, response to cold, and amino acid anabolism. The protein localises to the membrane, cytosol, plasmalemma, cytoplasm and nucleus. The gene is associated with seed yield, seed amino acid content, flowering time and plant stress response traits. Related genes in other species link this gene family to stress tolerance and flowering time.
