C-terminal W2 domain of eukaryotic translation initiation factor 4 gamma 1 and similar proteins; eIF4G1 is a component of the multi-subunit eukaryotic translation initiation factor 4F, which facilitates recruitment of the mRNA to the ribosome, a rate-limiting step during translation initiation. This C-terminal domain, whose structure resembles that of a set of concatenated HEAT repeats, has been associated with binding to/recruiting the kinase Mnk1, which phosphorylates eIF4E.

C-terminal W2 domain of eukaryotic translation initiation factor 2B epsilon; eIF2B is a heteropentameric complex which functions as a guanine nucleotide exchange factor in the recycling of eIF-2 during the initiation of translation in eukaryotes. The epsilon and gamma subunits are sequence similar and both are essential in yeast. Epsilon appears to be the catalytically active subunit, with gamma enhancing its activity. The C-terminal domain of the eIF2B epsilon subunit contains bipartite motifs rich in acidic and aromatic residues, which are responsible for the interaction with eIF2. The structure of the domain resembles that of a set of concatenated HEAT repeats.

C-terminal domain of eIF4-gamma/eIF5/eIF2b-epsilon; This domain is found at the C-terminus of several translation initiation factors, including the epsilon chain of eIF2b, where it has been found to catalyze the conversion of eIF2.GDP to its active eIF2.GTP form. The structure of the domain resembles that of a set of concatenated HEAT repeats.

C-terminal W2 domain of the eukaryotic translation initiation factor 5C and similar proteins; eIF5C appears to be essential for the initiation of protein translation; its actual function, and specifically that of the C-terminal W2 domain, are not well understood. The Drosophila ortholog, kra (krasavietz) or exba (extra bases), may be involved in translational inhibition in neural development. The structure of this C-terminal domain resembles that of a set of concatenated HEAT repeats.

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.

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
