KaiC domain (IPR010624)

Short name: KaiC_dom

Overlapping homologous superfamilies

Domain relationships


This entry represents a domain within bacterial and archaeal proteins, most of which are hypothetical. More than one copy is sometimes found in each protein in this entry. These include KaiC, which is one of the Kai proteins among which direct protein-protein association may be a critical process in the generation of circadian rhythms in cyanobacteria [PMID: 10064581].

The circadian clock protein KaiC, is encoded in the kaiABC operon that controls circadian rhythms and may be universal in Cyanobacteria. Each member contains two copies of this domain, which is also found in other proteins. KaiC performs autophosphorylation and acts as its own transcriptional repressor.
