ID:SMG9_HUMAN DESCRIPTION: RecName: Full=Protein SMG9; AltName: Full=Protein smg-9 homolog; FUNCTION: Involved in nonsense-mediated decay (NMD) of mRNAs containing premature stop codons. Is recruited by release factors to stalled ribosomes together with SMG1 and SMG8 (forming the SMG1C protein kinase complex) and, in the SMG1C complex, is required for the efficient association between SMG1 and SMG8. SUBUNIT: Component of the SMG1C complex composed of SMG1, SMG8 and SMG9. Self-associates to form homodimers and forms heterodimers with SMG8; these assembly forms may represent SMG1C intermediate forms. INTERACTION: Self; NbExp=3; IntAct=EBI-2872322, EBI-2872322; Q8ND04:SMG8; NbExp=4; IntAct=EBI-2872322, EBI-3903643; PTM: Phosphorylated by SMG1. SIMILARITY: Belongs to the SMG9 family. SEQUENCE CAUTION: Sequence=AAC17932.1; Type=Erroneous gene model prediction;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

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.
