简介
Stathmin proteins critically regulate the microtubule filament system by actively destabilizing microtubules, inhibiting assembly, and promoting disassembly. Phosphorylation of Ser-16 is critical for axon formation during neurogenesis, highlighting its importance in neuronal development. Stathmin Protein, Human (C-His) is the recombinant human-derived Stathmin protein, expressed by E. coli , with C-6*His labeled tag.

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
Stathmin, also known as oncoprotein 18, is a crucial regulatory protein involved in microtubule dynamics, influencing cell division, signaling pathways, and cytoskeletal organization. Discovered in the early 1990s, it has garnered significant interest due to its role in cancer progression and metastasis, as it is often overexpressed in various malignancies. Stathmin functions primarily by sequestering tubulin dimers, thereby preventing their assembly into microtubules, which is essential for maintaining cellular architecture and proper mitotic function. The dysregulation of stathmin activity can lead to aberrant cell proliferation and resistance to apoptosis, making it a potential therapeutic target. Recent studies have focused on the structure-function relationship of stathmin and the development of stathmin-targeting compounds. Recombining stathmin offers a means to study its functional properties in detail, facilitating a better understanding of its involvement in cellular processes and disease mechanisms. Moreover, elucidating the molecular mechanisms governing stathmin’s activity can inform the design of novel cancer therapies aimed at disrupting its pro-tumorigenic effects. This research not only enhances our fundamental knowledge of cell biology but also opens avenues for targeted interventions in cancer treatment.
