Tsen54 Gene Summary [Mouse]
Predicted to be involved in tRNA-type intron splice site recognition and cleavage. Predicted to be located in nucleolus. Predicted to be part of tRNA-intron endonuclease complex. Is expressed in cerebellum; retina inner nuclear layer; and retina outer nuclear layer. Human ortholog(s) of this gene implicated in pontocerebellar hypoplasia type 2A; pontocerebellar hypoplasia type 4; and pontocerebellar hypoplasia type 5. Orthologous to human TSEN54 (tRNA splicing endonuclease subunit 54). [provided by Alliance of Genome Resources, Jul 2025]

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 Tsen54 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
