Protein
Casein kinase II subunit alpha-3
Organism
Arabidopsis thaliana
Function
Casein kinases are operationally defined by their preferential utilization of acidic proteins such as caseins as substrates. The alpha chain contains the catalytic site. The tetrameric holoenzyme CK2 is composed of two alpha and two beta subunits (By similarity). Acts as circadian clock component that maintains the correct period length through phosphorylation of CCA1 (PubMed:21900482).
Similarity
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. CK2 subfamily.
