ID:SMG5_HUMAN DESCRIPTION: RecName: Full=Protein SMG5; AltName: Full=EST1-like protein B; AltName: Full=LPTS-RP1; AltName: Full=LPTS-interacting protein; AltName: Full=SMG-5 homolog; Short=hSMG-5; FUNCTION: Plays a role in nonsense-mediated mRNA decay. Does not have RNase activity by itself. Promotes dephosphorylation of UPF1. Together with SMG7 is thought to provide a link to the mRNA degradation machinery involving exonucleolytic pathways, and to serve as an adapter for UPF1 to protein phosphatase 2A (PP2A), thereby triggering UPF1 dephosphorylation. Necessary for TERT activity. SUBUNIT: Interacts with TERT, PPP2CA and SMG1. Part of a complex that contains SMG1, SMG5, SMG7, PPP2CA, a short isoform of UPF3A (isoform UPF3AS, but not isoform UPF3AL) and phosphorylated UPF1. Not detected in complexes that contain unphosphorylated UPF1. INTERACTION: Q92900-2:UPF1; NbExp=2; IntAct=EBI-3400861, EBI-373492; SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Note=Predominantly cytoplasmic, and nuclear. Shuttles between nucleus and cytoplasm. Detected in cytoplasmic mRNA decay bodies. TISSUE SPECIFICITY: Ubiquitous. SIMILARITY: Contains 1 PINc domain. SEQUENCE CAUTION: Sequence=BAA83041.2; Type=Erroneous initiation; Note=Translation N-terminally shortened;
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.
