| Note | THIS PRODUCT IS FOR RESEARCH USE ONLY. NOT FOR USE IN DIAGNOSTIC OR THERAPEUTIC PROCEDURES. The range and sensitivity is subject to change. Please contact us for the latest product information. For accurate results, sample concentrations must be diluted to mid-range of the kit. If you require a specific range, please contact us in advance or write your request in your order comments. Please note that our kits are optimised for detection of native samples, rather than recombinant proteins. We are unable to guarantee detection of recombinant proteins, as they may have different sequences or tertiary structures to the native protein. The stability of the kit is determined by the rate of activity loss. The loss rate is less than 5% within the expiration date under appropriate storage conditions. To minimize performance fluctuations, operation procedures and lab conditions should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same user throughout. |
Background
Stratifin (SFN) , also known as 14-3-3 sigma, is a member of the 14-3-3 protein family that acts as a critical regulator of cell cycle progression, DNA damage response, and cellular stress. It binds to phosphorylated serine/threonine residues on target proteins, facilitating their localization, stability, and activity. Stratifin is specifically involved in G2/M cell cycle checkpoint control by sequestering cyclin-dependent kinase complexes like CDC25C in the cytoplasm, preventing premature mitotic entry under DNA damage conditions. It is highly expressed in epithelial tissues and is essential for maintaining epithelial cell integrity, polarity, and stress responses. Stratifin acts as a tumor suppressor by inhibiting uncontrolled proliferation; its downregulation has been observed in breast, lung, and gastrointestinal cancers due to epigenetic silencing. Functional studies reveal its role in mediating stress-induced growth arrest and apoptosis, underscoring its importance in tumor suppression, DNA repair, and cell cycle regulation.
