SMG1

• PFAM accession number: PF15785
• Interpro abstract (IPR031559):

  Serine/threonine-protein kinase SMG1 is a phosphatidylinositol kinase-related protein that acts as an mRNA-surveillance protein and is a key component of nonsense-mediated decay (NMD) [ (PUBMED:11331269) (PUBMED:15175154) (PUBMED:12881430) (PUBMED:15314158) ]. In C.elegans, SMG1 is a key regulator of growth. Loss of SMG1 leads to hyperactive responses to injury and subsequent growth that continues out of control. It has an antagonistic role to mTOR signalling in worms [ (PUBMED:22479207) ] and possibly also in higher eukaryotes.

• GO process: phosphorylation (GO:0016310), nuclear-transcribed mRNA catabolic process, nonsense-mediated decay (GO:0000184)
• GO function: protein serine/threonine kinase activity (GO:0004674)
