ribosomal protein S3, bacterial type; This model describes the bacterial type of ribosomal protein S3. Chloroplast and mitochondrial forms have large, variable inserts between conserved N-terminal and C-terminal domains. This model recognizes all bacterial forms and many chloroplast forms above the trusted cutoff score. TIGRFAMs model TIGR01008 describes S3 of the eukaryotic cytosol and of the archaea.

type II K-homology (KH) RNA-binding domain found in 30S ribosomal protein S3 and similar proteins; 30S ribosomal protein S3, also called small ribosomal subunit protein uS3, is part of the head region of the 30S ribosomal subunit and binds to the lower part of the 30S subunit head. It may also bind mRNA in the 70S ribosome, positioning it for translation. S3 protein is believed to interact with mRNA as it threads its way from the latch into the channel. Members of this family contain only one canonical type II K-homology (KH) domain that has the signature motif GXXG (where X represents any amino acid).

Ribosomal protein S3, C-terminal domain; This family contains a central domain pfam00013, hence the amino and carboxyl terminal domains are stored separately. This is a minimal carboxyl-terminal domain. Some are much longer.

type II K-homology (KH) RNA-binding domain found in archaeal 30S ribosomal protein S3 and similar proteins; 30S ribosomal protein S3, also called small ribosomal subunit protein uS3, is part of the head region of the 30S ribosomal subunit and binds to the lower part of the 30S subunit head. It is believed to interact with mRNA as it threads its way from the latch into the channel. Members of this family are mainly from archaea and contain only one canonical type II K-homology (KH) domain that has the signature motif GXXG (where X represents any amino acid).

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,
or click on the triangles, if present, that represent functional sites (conserved features)
mapped to the query sequence.
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) Standard Display shows only the best scoring domain model from each source, in each hit category listed below 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)
the domain superfamily to which the specific and non-specific hits belong
multi-domain models that were computationally detected and are likely to contain multiple single domains
