Sepsecs Gene Summary [Mouse]

Enables tRNA binding activity. Involved in selenocysteine incorporation. Located in cytoplasm and nucleus. Is expressed in several structures, including alimentary system; cerebral cortex; genitourinary system; musculoskeletal system; and respiratory system. Human ortholog(s) of this gene implicated in pontocerebellar hypoplasia type 2D. Orthologous to human SEPSECS (Sep (O-phosphoserine) tRNA:Sec (selenocysteine) tRNA synthase).

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 Sepsecs often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
