Summary: 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, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
