Overview of Gene Research
Fbxo11, also known as VIT1 and PRMT9, is the substrate-recognition component of the Skp1-Cullin-1-F-box (SCF) E3 ubiquitin-ligase complex. It is involved in ubiquitin-dependent proteasomal degradation processes, which play crucial roles in various biological pathways such as immune regulation, bone development, lipid metabolism, and antiviral responses [1,2,3,4]. Genetic models, especially gene knockout (KO) and conditional knockout (CKO) mouse models, have been valuable in studying its functions.
In KO/CKO mouse models, osteoblastic-specific FBXO11 deficiency inhibits normal bone growth and osteogenic activity through Snail1 protein accumulation, demonstrating its role in bone development [2]. In immune-related studies, FBXO11 deficiency in human and mouse cells leads to increased levels of MHC-II and related genes, indicating its negative regulation of MHC-II through ubiquitination-mediated degradation of CIITA [1].
In conclusion, Fbxo11 is essential for multiple biological functions mainly through its role in the ubiquitination-mediated degradation of key proteins. Studies using KO/CKO mouse models have revealed its importance in bone development and immune regulation, which may provide insights into related disease mechanisms such as bone growth disorders and immune-related cancers [1,2].
