KaiA is essential for circadian timekeeping. This protein organised into two domains. This entry represents the a pseudo-receiver domain, which has a similar fold with that of bacterial response regulators, with an alpha-beta structure [1-5].

PF07688KaiA C-terminal domain (KaiA)KaiA C-terminal domainThe cyanobacterial clock proteins KaiA and KaiB are proposed as regulators of the circadian rhythm in cyanobacteria. The overall fold of the KaiA C-terminal domain is that of a four-helix bundle, which forms a dimer in the known structure [1].Domain
