Usp8 Gene Summary [Mouse]
Enables cysteine-type deubiquitinase activity. Involved in endosome organization and protein deubiquitination. Acts upstream of or within Ras protein signal transduction. Located in cytoplasmic vesicle membrane; cytosol; and midbody. Is expressed in several structures, including brain; genitourinary system; gut; hemolymphoid system gland; and sensory organ. Human ortholog(s) of this gene implicated in ACTH-secreting pituitary adenoma. Orthologous to human USP8 (ubiquitin specific peptidase 8). [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 Usp8 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
