Smg1 Gene Summary [Mouse]
Predicted to enable diacylglycerol-dependent serine/threonine kinase activity and telomeric DNA binding activity. Predicted to be involved in several processes, including nuclear-transcribed mRNA catabolic process, nonsense-mediated decay; phosphatidylinositol phosphate biosynthetic process; and protein phosphorylation. Located in chromatoid body. Is expressed in cerebral cortex; early embryo; and germ cell of testis. Orthologous to human SMG1 (SMG1 nonsense mediated mRNA decay associated PI3K related kinase).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Smg1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
