F-box/SPRY domain-containing protein 1

Gene

FBXO45

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Component of E3 ubiquitin ligase complexes. Required for normal neuromuscular synaptogenesis, axon pathfinding and neuronal migration (By similarity). Plays a role in the regulation of neurotransmission at mature neurons (By similarity). May controls synaptic activity by controlling UNC13A via ubiquitin dependent pathway (By similarity). Specifically recognizes TP73, promoting its ubiquitination and degradation.By similarity1 Publication

Interactioni

Subunit structurei

Forms a complex with MYCBP2 and SKP1 but does not appear to form an authentic SCF (SKP1-CUL1-F-box protein) complex (By similarity). Interacts (via B30.2/SPRY domain) with TP73 (via SAM domain); leading to TP73 ubiquitination and degradation by proteasome. Interacts (via SRY domain) with UNC13A; leading to degradation of UNC13A by the proteasome (By similarity).By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
