Cullin 4A (CUL4A) is a core component of the Cullin-RING E3 ubiquitin ligase (CRL) complexes, which mediate the ubiquitination of substrate proteins for proteasomal degradation. As a scaffold protein, CUL4A assembles with adaptors like DDB1 and substrate receptors to form functional ligases regulating DNA repair, cell cycle progression, chromatin remodeling, and transcriptional control. Its activity is critical for maintaining genomic stability and cellular homeostasis.
CUL4A antibodies are essential tools for studying its expression, localization, and interactions in biological systems. They are widely used in techniques such as Western blotting, immunoprecipitation, and immunofluorescence to investigate CUL4A's role in diseases, including cancers (e.g., breast, lung, and liver cancers), viral infections (e.g., HIV and HPV), and genetic disorders like Cockayne syndrome. Dysregulation of CUL4A has been linked to abnormal protein degradation, impaired DNA damage response, and oncogenic signaling.
Research utilizing CUL4A antibodies has also explored its potential as a therapeutic target, particularly in cancers where CRL4A complexes promote tumor progression by destabilizing tumor suppressors. These antibodies help identify molecular mechanisms underlying drug resistance and inform the development of inhibitors like MLN4924. which blocks Cullin neddylation to suppress CRL activity. Overall, CUL4A antibodies are pivotal in unraveling its multifaceted roles in health and disease.
