Function. Involved in nonsense-mediated decay (NMD) of mRNAs containing premature stop codons. Is recruited by release factors to stalled ribosomes together with SMG1 and SMG9 (forming the SMG1C protein kinase complex) and, in the SMG1C complex, is required to mediate the recruitment of SMG1 to the ribosome:SURF complex and to suppress SMG1 kinase activity until the ribosome:SURF complex locates the exon junction complex (EJC). Acts as a regulator of kinase activity.
Subunit / interactions. Component of the SMG1C complex composed of SMG1, SMG8 and SMG9; the recruitment of SMG8 to SMG1 N-terminus induces a large conformational change in the SMG1 C-terminal head domain containing the catalytic domain. Forms heterodimers with SMG9; this assembly form may represent a SMG1C intermediate form.
Post-translational modifications. Phosphorylated by SMG1.
Disease relevance. Alzahrani-Kuwahara syndrome (ALKUS) [MIM:619268] An autosomal recessive disorder characterized by severe global developmental delay, impaired intellectual function, poor or absent speech, microcephaly, and facial dysmorphism. Additional variable features include early-onset cataracts, hypotonia, lower limb spasticity, and congenital heart malformations. The disease is caused by variants affecting the gene represented in this entry.
Similarity. Belongs to the SMG8 family.
