FBXO7 (F-box only protein 7) is a substrate recognition component of the SCF (Skp1-Cul1-F-box) ubiquitin ligase complex. It plays critical roles in mitochondrial quality control, mitophagy, and neuronal survival. Pathogenic variants in FBXO7 cause autosomal recessive Parkinson's disease (PD)[@fbxo2024].
FBXO7 contains multiple functional domains[@fbxo2024a]:
FBXO7 is essential for Parkin-independent mitophagy[@fbxo2024b]:
Although FBXO7 functions independently of PINK1/Parkin:

FBXO7 represents a critical node in neuronal mitochondrial quality control and ubiquitin-dependent protein degradation. Its involvement in Parkinson's disease through autosomal recessive inheritance, combined with its broader roles in protein homeostasis and cellular stress responses, makes it an important therapeutic target. Continued research into FBXO7 biology and therapeutic modulation holds promise for disease-modifying treatments in Parkinson's and related neurodegenerative disorders.
