Component of E3 ubiquitin ligase complexes. Required for normal neuromuscular synaptogenesis, axon pathfinding and neuronal migration. Plays a role in the regulation of neurotransmission at mature neurons. May controls synaptic activity by controlling UNC13A via ubiquitin dependent pathway. Specifically recognizes TP73, promoting its ubiquitination and degradation.
F-box only protein 45; F-box/SPRY domain-containing protein 1; hFbxo45
