简介
The USP44 protein is a key deubiquitinase that regulates the spindle assembly checkpoint and prevents premature initiation of anaphase by deubiquitinating CDC20. This stabilizes the MAD2L1-CDC20-APC/C complex and enhances the spindle assembly checkpoint. USP44 Protein, Human is the recombinant human-derived USP44 protein, expressed by E. coli , with tag free.

稳定性测试
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Protein Description
USP44 (Ubiquitin Specific Peptidase 44) is an important member of the ubiquitin-specific protease family, known for its role in regulating cellular processes through the removal of ubiquitin moieties from target proteins. Research into USP44 has garnered significant attention due to its critical involvement in cell cycle regulation, particularly in the maintenance of genomic stability. Recent studies have highlighted its function in preventing premature anaphase onset by deubiquitinating key substrates involved in the anaphase-promoting complex/cyclosome (APC/C) pathway, thereby influencing the degradation of proteins necessary for chromosome segregation. Additionally, aberrant expression or mutation of USP44 has been implicated in various cancers, suggesting its potential role as a tumor suppressor and a prospective target for therapeutic interventions. The exploration of USP44's structure and function, including its enzymatic mechanisms, has opened avenues for developing specific inhibitors that can modulate its activity. Moreover, understanding the interplay between USP44 and other cellular signaling pathways is essential for elucidating its comprehensive role in cell biology and pathology. This underscores the significance of USP44 in both basic research and potential clinical applications, making it a valuable focus for ongoing studies in cancer biology and therapeutic research.
