Psme4 Gene Summary [Mouse]
Enables lysine-acetylated histone binding activity and peptidase activator activity. Involved in DNA repair; proteasomal ubiquitin-independent protein catabolic process; and sperm DNA condensation. Located in cytosol and nucleus. Part of spermatoproteasome complex. Is expressed in craniocervical region bone; nervous system; sensory organ; and submandibular gland primordium. Used to study visceral heterotaxy. Orthologous to human PSME4 (proteasome activator subunit 4). [provided by Alliance of Genome Resources, Apr 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 Psme4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- histone binding
- Proteasome-substrate-size regulator, mid region
- Domain of unknown function (DUF3437)
- protein binding
