kaiB

Gene
kaiB
Protein
Circadian clock protein KaiB
Organism
Prochlorococcus marinus (strain MIT 9303)
Length
119 amino acids
Function
Component of the KaiABC clock protein complex, which constitutes the main circadian regulator in cyanobacteria. The KaiABC complex may act as a promoter-non-specific transcription regulator that represses transcription, possibly by acting on the state of chromosome compaction. In the complex, it decreases the phosphorylation status of KaiC. It has no effect on KaiC by itself, but instead needs the presence of both KaiA and KaiC, suggesting that it acts by antagonizing the interaction between KaiA and KaiC.
Similarity
Belongs to the KaiB family.
