Function edit

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. Alternative spliced transcript variants have been described, but their full-length natures have not been determined.[8]

Interactions edit

SMG1 (gene) has been shown to interact with PRKCI[9] and UPF1.[10]
