mRNA decapping enzyme 1 (Dcp1); mRNA decapping enzyme 1 (Dcp1), together with Dcp2, is part of the decapping complex which catalyzes the removal of the 5' cap structure of mRNA. This decapping reaction is an essential step in mRNA degradation, by exposing the 5' end for exonucleolytic digestion. Dcp1 binds to the N-terminal helical domain of catalytic subunit Dcp2 and enhances its function by promoting Dsp2's closed conformation which is catalytically more active.

Dcp1-like decapping family; An essential step in mRNA turnover is decapping. In yeast, two proteins have been identified that are essential for decapping, Dcp1 (this family) and Dcp2 (pfam05026). The precise role of these proteins in the decapping reaction have not been established. Evidence suggests that the Dcp1 may enhance the function of Dcp2.

Decapping enzyme EVH1-like domain; Dcp1 is a small protein containing an EVH1 domain. The Dcp1-Dcp2 complex plays a critical step in mRNA degradation with the removal of the 50 cap structure. Dcp1 stimulates the activity of Dcp2 by promoting and/or stabilizing the closed complex. The interface of Dcp1 and Dcp2 is not fully conserved and in higher eukaryotes it requires an additional factor. The proline-rich sequence (PRS)-binding sites in Dcp1p indicates that it belongs to a novel class of EVH1 domains. Dcp1 has 2 prominent sites,one required for the function of the Dcp1p-Dcp2p complex, and the other, the PRS-binding site of EVH1 domains, a binding site for decapping regulatory proteins. It also has a conserved hydrophobic patch is shown to be critical for decapping. The EVH1 domains are part of the PH domain superamily.

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)
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
