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.

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.
