FBXO21 (F-Box Protein 21): FBXO21 is part of the F-box protein family, key components in the ubiquitin-proteasome system, which regulates protein degradation. This gene plays a crucial role in various cellular processes, including cell cycle regulation and signal transduction. Dysregulation of FBXO21 can lead to disorders in protein homeostasis, making it significant in the study of diseases where protein turnover is disrupted, such as neurodegenerative diseases and cancers....
