== Function ==
[https://www.uniprot.org/uniprot/KAIC_SYNE7 KAIC_SYNE7] Core component of the KaiABC clock protein complex, which constitutes the main circadian regulator in cyanobacteria. Binds to DNA. The KaiABC complex may act as a promoter-nonspecific transcription regulator that represses transcription, possibly by acting on the state of chromosome compaction.<ref>PMID:9727980</ref> <ref>PMID:14709675</ref>
