>cd02978 KaiB_like KaiB-like family; composed of the circadian clock proteins, KaiB and the N-terminal KaiB-like sensory domain of SasA. KaiB is an essential protein in maintaining circadian rhythm. It was originally discovered from the cyanobacterium Synechococcus as part of the circadian clock gene cluster, kaiABC. KaiB attenuates KaiA-enhanced KaiC autokinase activity by interacting with KaiA-KaiC complexes in a circadian fashion. KaiB is membrane-associated as well as cytosolic. The amount of membrane-associated protein peaks in the evening (at circadian time (CT) 12-16) while the cytosolic form peaks later (at CT 20). The rhythmic localization of KaiB may function in regulating the formation of Kai complexes. SasA is a sensory histidine kinase which associates with KaiC. Although it is not an essential oscillator component, it is important in enhancing kaiABC expression and is important in metabolic growth control under day/night cycle conditions. SasA contains an N-terminal sensor
