Secondary Information

Protein Function FBXL7, encodes a subcellular protein involved in phosphorylation-dependent ubiquitination processes and displays proapoptotic activity. F-box proteins also modulate inflammation and innate immunity, which may be important in late-onset Alzheimer's disease (LOAD) pathogenesis.
Biochemical Properties F-box/LRR-repeat protein 2 (FBXL2), a component of Skp-Cullin-F box (SCF) ubiquitin E3 ligase, has been shown to inhibit tumorigenesis by targeting and ubiquitinating several oncoproteins.

Significance of PTMs SUMOylation and deSUMOylation, was implicated in the regulation of FoxM1 transcriptional activity.FBXL2 is phosphorylated by GSK3b for the proper regulation in gastric cancer.
Additional Comments Overexpression of FBXL2 inhibits, while its deficiency promotes cell proliferation and invasion.
