Cache is an extracellular domain that is predicted to have a role in small-molecule recognition in a wide range of proteins; Members include the animal dihydropyridine-sensitive voltage-gated Ca2+ channel; alpha-2delta subunit, and various bacterial chemotaxis receptors. The name Cache comes from CAlcium channels and CHEmotaxis receptors. This domain consists of an N-terminal part with three predicted strands and an alpha-helix, and a C-terminal part with a strand dyad followed by a relatively unstructured region. The N-terminal portion of the (unpermuted) Cache domain contains three predicted strands that could form a sheet analogous to that present in the core of the PAS domain structure. Cache domains are particularly widespread in bacteria, with Vibrio cholerae. The animal calcium channel alpha-2delta subunits might have acquired a part of their extracellular domains from a bacterial source. The Cache domain appears to have arisen from the GAF-PAS fold despite their divergent functions.

second PDC (PhoQ/DcuS/CitA) domain of methyl-accepting chemotaxis proteins, diguanylate-cyclase and similar domains; Histidine kinase (HK) receptors are part of two-component systems (TCS) in bacteria that play a critical role for sensing and adapting to environmental changes. Typically, HK receptors contain an extracellular sensing domain flanked by two transmembrane helices, an intracellular dimerization histidine phosphorylation domain (DHp), and a C-terminal kinase domain, with many variations on this theme. HK receptors in this family contain double PDC (PhoQ/DcuS/CitA) sensor domains. Signals detected by the sensor domain are transmitted through DHp to the kinase domain, resulting in the phosphorylation of a conserved histidine residue in DHp; phosphotransfer to a conserved aspartate in its cognate response regulator (RR) follows, which leads to the activation of genes for downstream cellular responses. The HK family includes not just histidine kinase receptors but also sensors for chemotaxis proteins and diguanylate cyclase receptors, implying a combinatorial molecular evolution.

Histidine kinase-like ATPase domain of RsbW, an anti sigma-B factor and serine-protein kinase involved in regulating sigma-B during stress in Bacilli, and related domains; This family includes histidine kinase-like ATPase (HATPase) domain of RsbW, an anti sigma-B factor as well as a serine-protein kinase involved in regulating sigma-B during stress in Bacilli. The alternative sigma factor sigma-B is an important regulator of the general stress response of Bacillus cereus and B. subtilis. RsbW is an anti-sigma factor while RsbV is an anti-sigma factor antagonist (anti-anti-sigma factor). RsbW can also act as a kinase on RsbV. In a partner-switching mechanism, RsbW, RsbV, and sigma-B participate as follows: in non-stressed cells, sigma-B is present in an inactive form complexed with RsbW; in this form, sigma-B is unable to bind to RNA polymerase. Under stress, RsbV binds to RsbW, forming an RsbV-RsbW complex, and sigma-B is released to bind to RNA polymerase. RsbW may then act as a kinase on RsbV, phosphorylating a serine residue; RsbW is then released to bind to sigma-B, hence blocking its ability to bind RNA polymerase. A phosphatase then dephosphorylates RsbV so that it can again form a complex with RsbW, leading to the release of sigma-B.

second PDC (PhoQ/DcuS/CitA) domain of methyl-accepting chemotaxis proteins and similar domains; Members of this subfamily display varying domain architectures but all contain double PDC (PhoQ/DcuS/CitA) sensor domains. This model represents the second PDC domain of Methyl-accepting chemotaxis proteins (MCPs), Histidine kinases (HKs), and other similar domains. Many members contain both HAMP (HK, Adenylyl cyclase, MCP, and Phosphatase) and MCP domains, which are signalling domains that interact with protein partners to relay a signal. MCPs are part of a transmembrane protein complex that controls bacterial chemotaxis. HK receptors are part of two-component systems (TCS) in bacteria that play a critical role for sensing and adapting to environmental changes. Typically, HK receptors contain an extracellular sensing domain flanked by two transmembrane helices, an intracellular dimerization histidine phosphorylation domain (DHp), and a C-terminal kinase domain, with many variations on this theme. In the case of HKs, signals detected by the sensor domain are transmitted through DHp to the kinase domain, resulting in the phosphorylation of a conserved histidine residue in DHp; phosphotransfer to a conserved aspartate in its cognate response regulator (RR) follows, which leads to the activation of genes for downstream cellular responses.

Histidine kinase-like ATPase domain of two-component sensor histidine kinases similar to Erythrobacter litoralis blue light-activated histidine kinase 2; This domain family includes the histidine kinase-like ATPase (HATPase) domain of blue light-activated histidine kinase 2 of Erythrobacter litoralis (EL346). Signaling commonly occurs within HK dimers, however EL346 functions as a monomer. Also included in this family are the HATPase domains of ethanolamine utilization sensory transduction histidine kinase (EutW), whereby regulation of ethanolamine, a carbon and nitrogen source for gut bacteria, results in autophosphorylation and subsequent phosphoryl transfer to a response regulator (EutV) containing an RNA-binding domain. Proteins having this HATPase domain also contain a histidine kinase dimerization and phosphoacceptor domain (HisKA); some have an accessory PAS sensor domain, while some have an N-terminal histidine kinase domain.
