Summary: This gene encodes a protein involved in nonsense-mediated mRNA decay (NMD) as part of the mRNA surveillance complex. The protein has kinase activity and is thought to function in NMD by phosphorylating the regulator of nonsense transcripts 1 protein. Alternatively spliced transcript variants have been described, but their full-length nature has yet to be determined. [provided by RefSeq, Mar 2013]
Expression: Ubiquitous expression in skin (RPKM 20.7), bone marrow (RPKM 12.3) and 25 other tissues See more

SMG-1 is a target of the oncomiRs, miR-192 and -215, and that its downregulation is associated with tumor size and serosal invasion of gastric cancer (GC). SMG-1 appears to mediate at least some of the oncogenic function of miR-192 and -215 by participating in epithelial-mesenchymal transition, triggered by activation of the Wnt pathway in GC.
Title: SMG-1 inhibition by miR-192/-215 causes epithelial-mesenchymal transition in gastric carcinogenesis via activation of Wnt signaling.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
