Component of the decapping complex necessary for the degradation of mRNAs, both in normal mRNA turnover and in nonsense-mediated mRNA decay. Removes the 7-methyl guanine cap structure from mRNA molecules, yielding a 5'-phosphorylated mRNA fragment and 7m-GDP. Decapping is the major pathway of mRNA degradation in yeast. It occurs through deadenylation, decapping and subsequent 5' to 3' exonucleolytic decay of the transcript body.
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. Length = 121
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. Length = 116
>gnl|CDD|147945 pfam06058, DCP1, 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. Length = 123
In yeast, two proteins have been identified that are essential for decapping, Dcp1 (this family) and Dcp2 (IPR007722 from INTERPRO). The precise role of these proteins in the decapping reaction has not been established. Evidence suggests that the Dcp1 may enhance the function of Dcp2 [].; PDB: 1Q67_A 2QKM_C 2QKL_A.
EVH1 (Enabled, Vasp-Homology) or WASP Homology (WH1) domain. The EVH1 domain binds to other proteins at proline rich sequences in either FPPPP or PPXXF motifs. It is found in the cytoskeletal reorganization proteins Enabled VASP, and WASP, and in the synaptic scaffolding protein Homer. It has a PH-like fold, despite having minimal sequence similarity to PH or PTB domains.
Ran-binding domain; This domain of approximately 150 residues shares structural similarity to the PH domain, but lacks detectable sequence similarity. Ran is a Ras-like nuclear small GTPase, which regulates receptor-mediated transport between the nucleus and the cytoplasm. RanGTP hydrolysis is stimulated by RanGAP together with the Ran-binding domain containing acessory proteins RanBP1 and RanBP2. These accessory proteins stabilize the active GTP-bound form of Ran . The Ran-binding domain is found in multiple copies in Nuclear pore complex proteins.
>PF00568 WH1: WH1 domain; InterPro: IPR000697 The EVH1 (WH1, RanBP1-WASP) domain is found in multi-domain proteins implicated in a diverse range of signalling, nuclear transport and cytoskeletal events
This domain of around 115 amino acids is present in species ranging from yeast to mammals. Many EVH1-containing proteins associate with actin-based structures and play a role in cytoskeletal organisation. EVH1 domains recognise and bind the proline-rich motif FPPPP with low-affinity, further interactions then form between flanking residues [][]. WASP family proteins contain a EVH1 (WH1) in their N-terminals which bind proline-rich sequences in the WASP interacting protein. Proteins of the RanBP1 family contain a WH1 domain in their N-terminal region, which seems to bind a different sequence motif present in the C-terminal part of RanGTP protein [,]. Tertiary structure of the WH1 domain of the Mena protein revealed structure similarities with the pleckstrin homology (PH) domain. The overall fold consists of a compact parallel beta-sandwich, closed along one edge by a long alpha-helix. A highly conserved cluster of three surface-exposed aromatic side-chains forms the recognition site for the molecules target ligands.

>PF00638 Ran_BP1: RanBP1 domain; InterPro: IPR000156 Ran is an evolutionary conserved member of the Ras superfamily that regulates all receptor-mediated transport between the nucleus and the cytoplasm
Ran Binding Protein 1 (RanBP1) has guanine nucleotide dissociation inhibitory activity, specific for the GTP form of Ran and also functions to stimulate Ran GTPase activating protein(GAP)-mediated GTP hydrolysis by Ran. RanBP1 contributes to maintaining the gradient of RanGTP across the nuclear envelope high (GDI activity) or the cytoplasmic levels of RanGTP low (GAP cofactor) []. All RanBP1 proteins contain an approx 150 amino acid residue Ran binding domain. Ran BP1 binds directly to RanGTP with high affinity. There are four sites of contact between Ran and the Ran binding domain. One of these involves binding of the C-terminal segment of Ran to a groove on the Ran binding domain that is analogous to the surface utilised in the EVH1-peptide interaction []. Nup358 contains four Ran binding domains. The structure of the first of these is known [].; GO: 0046907 intracellular transport; PDB: 2Y8F_A 2Y8G_B 2CRF_A 1XKE_A 1RRP_D 2EC1_A 3M1I_B 1K5D_E 3OAN_A 3N7C_A ....
