Predicted to be involved in SCF-dependent proteasomal ubiquitin-dependent protein catabolic process; regulation of protein catabolic process at presynapse, modulating synaptic transmission; and regulation of synaptic vesicle exocytosis. Predicted to act upstream of or within behavioral fear response. Predicted to be located in Schaffer collateral - CA1 synapse. Predicted to be part of SCF ubiquitin ligase complex. Predicted to be active in glutamatergic synapse. Orthologous to human FBXL20 (F-box and leucine rich repeat protein 20). [provided by Alliance of Genome Resources, Apr 2022]
