MAGOH is an important spliceosome component that cooperates with MAGOHB to form the exon junction complex (EJC), which is central to pre-mRNA splicing and nonsense-mediated decay (NMD). EJC affects mRNA metabolism, marks exon-exon junctions, and affects processes such as mRNA export, localization, translation, and NMD. MAGOH Protein, Human (His) is the recombinant human-derived MAGOH protein, expressed by E. coli , with C-6*His labeled tag.
