Fbxo45 Gene Summary [Mouse]
Predicted to enable ubiquitin-like ligase-substrate adaptor activity. Involved in proteasome-mediated ubiquitin-dependent protein catabolic process; protein ubiquitination; and regulation of synaptic vesicle exocytosis. Acts upstream of or within nervous system development. Located in postsynaptic density. Is active in glutamatergic synapse; postsynaptic cytosol; and presynaptic cytosol. Is expressed in nervous system. Orthologous to human FBXO45 (F-box protein 45). [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 Fbxo45 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
