GENE INFORMATION
Gene name	SMG1 (HGNC Symbol)
Synonyms	ATX, KIAA0421, LIP
Description	SMG1 phosphatidylinositol 3-kinase-related kinase (HGNC Symbol)
Entrez gene 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]
