CheW-like domain. CheW proteins are part of the chemotaxis signalling mechanism in bacteria. CheW interacts with the methyl accepting chemotaxis proteins (MCPs) and relays signals to CheY, which affects flageller rotation. This family includes CheW and other related proteins that are involved in chemotaxis. The CheW-like regulatory domain in the chemotaxis associated histidine kinase CheA binds to CheW, suggesting that these domains can interact with each other.

CheW, a small regulator protein, unique to the chemotaxis signalling in prokaryotes and archea. CheW interacts with the histidine kinase CheA, most likely with the related regulatory domain of CheA. CheW is proposed to form signalling arrays together with CheA and the methyl-accepting chemotaxis proteins (MCPs), which are involved in response modulation.

CheA regulatory domain; CheA is a histidine protein kinase present in bacteria and archea. Activated by the chemotaxis receptor a histidine phosphoryl group from CheA is passed directly to an aspartate in the response regulator CheY. This signalling mechanism is modulated by the methyl accepting chemotaxis proteins (MCPs). MCPs form a highly interconnected, tightly packed array within the membrane that is organized, at least in part, through interactions with CheW and CheA. The CheA regulatory domain belongs to the family of CheW_like proteins and has been proposed to mediate interaction with the kinase regulator CheW.

of the residues that compose this conserved feature have been mapped to the query sequence.
Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.
The thumbnail image, if present, provides an approximate view of the feature's location in 3 dimensions.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.
To view your query sequence embedded in that multiple sequence alignment, click on the colored bars in the Graphical Summary portion of the search results page,

Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.

(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
