Summary: Enables protein phosphatase 2A binding activity. Involved in embryonic genitalia morphogenesis and negative regulation of gene expression. Located in cytoplasm and nucleus. Is expressed in intestinal cell; muscle cell; and nervous system. Orthologous to human UPF1 (UPF1 RNA helicase and ATPase). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

SMG-2 interacts with SMG-3, SMG-3 interacts with SMG-4, and SMG-2 interacts indirectly with SMG-4 via shared interactions with SMG-3. SMG-2 preferentially associates with PTC-containing mRNAs.
Title: Caenorhabditis elegans SMG-2 selectively marks mRNAs containing premature translation termination codons.
results suggest that the role of SMG-5 is to direct protein phosphatase 2A to its SMG-2 substrate
Title: SMG-5, required for C.elegans nonsense-mediated mRNA decay, associates with SMG-2 and protein phosphatase 2A.
