Human Gene DCP1A (uc021wzi.1) Description and Page Index
  Description: Homo sapiens decapping mRNA 1A (DCP1A), mRNA.
RefSeq Summary (NM_018403): Decapping is a key step in general and regulated mRNA decay. The protein encoded by this gene is a decapping enzyme. This protein and another decapping enzyme form a decapping complex, which interacts with the nonsense-mediated decay factor hUpf1 and may be recruited to mRNAs containing premature termination codons. This protein also participates in the TGF-beta signaling pathway. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Feb 2014].

DESCRIPTION: RecName: Full=mRNA-decapping enzyme 1A; EC=3.-.-.-; AltName: Full=Smad4-interacting transcriptional co-activator; AltName: Full=Transcription factor SMIF;
FUNCTION: 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. Contributes to the transactivation of target genes after stimulation by TGFB1.
SUBUNIT: Forms a complex with EDC3, DCP2, DDX6 and EDC4/HEDLS, within this complex directly interacts with EDC3. Binds DCP1B, UPF1 and SMAD4. Part of a cytoplasmic complex containing proteins involved in mRNA decay, including XRN1 and LSM1. Interacts with PNRC2. Interacts with DDX17 in an RNA-independent manner. Interacts with ZC3HAV1.
INTERACTION: Self; NbExp=4; IntAct=EBI-374238, EBI-374238; Q8IU60:DCP2; NbExp=6; IntAct=EBI-374238, EBI-521577; P26196:DDX6; NbExp=4; IntAct=EBI-374238, EBI-351257; Q92900:UPF1; NbExp=13; IntAct=EBI-374238, EBI-373471; P26651:ZFP36; NbExp=2; IntAct=EBI-374238, EBI-374248;
SUBCELLULAR LOCATION: Cytoplasm, P-body. Nucleus. Note=Co- localizes with NANOS3 in the processing bodies (By similarity). Predominantly cytoplasmic, in processing bodies (PB). Nuclear, after TGFB1 treatment. Translocation to the nucleus depends on interaction with SMAD4.
TISSUE SPECIFICITY: Detected in heart, brain, placenta, lung, skeletal muscle, liver, kidney and pancreas.
SIMILARITY: Belongs to the DCP1 family.

    In hypothesis-generating GWAS of echocardiography, ETT and BA vascular function in a moderate-sized community-based sample, we identified several SNPs that are candidates for replication attempts and we provide a web-based GWAS resource for the research community.
  2. Blood Pressure
    Daniel Levy et al. BMC medical genetics 2007, Framingham Heart Study 100K Project: genome-wide associations for blood pressure and arterial stiffness., BMC medical genetics. [PubMed 17903302]
    These results of genome-wide association testing for blood pressure and arterial stiffness phenotypes in an unselected community-based sample of adults may aid in the identification of the genetic basis of hypertension and arterial disease, help identify high risk individuals, and guide novel therapies for hypertension. Additional studies are needed to replicate any associations identified in these analyses.

ModBase Predicted Comparative 3D Structure on Q9NPI6
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
