CKB3

Gene
CKB3
Protein
Casein kinase II subunit beta-3
Organism
Arabidopsis thaliana
Length
276 amino acids
Function
Plays a complex role in regulating the basal catalytic activity of the alpha subunit. The tetrameric holoenzyme CK2, composed of two alpha and two beta subunits, phosphorylates the transcription factor PIF1 after an exposure to light, resulting in a proteasome-dependent degradation of PIF1 and promotion of photomorphogenesis (PubMed:21330376). CK2 phosphorylates translation initiation factors. May participate in the regulation of the initiation of translation (PubMed:19509278). Stimulates the binding of CCA1 to promoters (Probable).
Similarity
Belongs to the casein kinase 2 subunit beta family.
