FBXO32(F-box protein 32,又称Atrogin-1或MAFbx)是一种属于F-box蛋白家族的基因,该家族成员共同特点是含有F-box结构域,能够与SKP1、Cullin等蛋白组成SCF(Skp1-Cullin-F-box)泛素连接酶复合物,负责标记特定蛋白质使其被蛋白酶体降解(泛素-蛋白酶体系统是细胞内清除异常或受损蛋白质的重要机制)。FBXO32主要在骨骼肌和心肌中高表达,其核心功能是通过泛素化降解靶蛋白来调控肌肉萎缩过程,例如它可特异性识别并降解收缩蛋白如肌球蛋白重链(MyHC)以及调控肌肉生长的关键转录因子如MyoD。FBXO32的突变或异常表达与多种肌肉疾病相关,其过度激活会导致肌肉萎缩(如癌症恶病质、心力衰竭或长期卧床引起的肌肉流失),而敲除该基因的小鼠则表现出对抗肌肉萎缩的能力。该基因的表达受FoxO转录因子和肌肉萎缩信号通路(如TGF-β/SMAD、NF-κB)的调控,在禁食、糖皮质激素或炎症因子刺激下表达显著上调。FBXO32属于FBXO亚家族(F-box only proteins),该家族共性是通过可变C端结构域识别不同底物,参与细胞周期、代谢、信号传导等过程的蛋白质稳态调控。若FBXO32过表达会加速肌肉蛋白降解导致萎缩,而表达不足则可能影响正常蛋白质更新或导致异常蛋白堆积。此外,FBXO32还与神经退行性疾病(如阿尔茨海默病)中异常蛋白清除障碍有关,其表达水平变化可能影响tau蛋白等病理蛋白的清除效率。

This gene encodes a member of the F-box protein family which is characterized by an approximately 40 amino acid motif, the F-box. The F-box proteins constitute one of the four subunits of the ubiquitin protein ligase complex called SCFs (SKP1-cullin-F-box), which function in phosphorylation-dependent ubiquitination. The F-box proteins are divided into 3 classes: Fbws containing WD-40 domains, Fbls containing leucine-rich repeats, and Fbxs containing either different protein-protein interaction modules or no recognizable motifs. The protein encoded by this gene belongs to the Fbxs class and contains an F-box domain. This protein is highly expressed during muscle atrophy, whereas mice deficient in this gene were found to be resistant to atrophy. This protein is thus a potential drug target for the treatment of muscle atrophy. Alternative splicing results in multiple transcript variants encoding different isoforms.
