Uses
Vimentin, His tagged human has been used in the glass surface immobilization in anti-vimentin binding in force measurement by atomic force microscopy (AFM).
General Description
Vimentin belongs to the intermediate filament family of proteins. It is a key structural component of eukaryotic cells and is associated with lymphocytes and neutrophils. Vimentin exists as a tripartite domain structure. It is expressed in mesenchymal cells. The vimentin gene is mapped to human chromosome 10p13.
Biochem/physiol Actions
Vimentin (VIM) stabilizes cytoskeletal interactions and is crucial for the placement of organelles in the cytosol. It modulates apoptosis in lymphocytes and is involved in the pathogenesis of inflammatory diseases VIM may serve as a potential marker for sepsis diagnosis. It is also essential for lens integrity maintenance.
Description
Bovine Vimentin protein produced in Bovine Lens, having a molecular weight of 57 kDa.
Background
Vimentin expression in human malignant glioma cells depends on cellular density, algorithms of drug delivery and chemo/radio treatment. Vimentin and detyrosinated microtubules provide structural support for the extensive microtentacles observed in detached tumor cells and a mechanism to promote successful metastatic spread. Primary colorectal carcinomas display aberrant expression of vimentin, and have activated Notch and TGFbeta signaling pathways. Vimentin is a strong arterial substrate for transglutaminases. Transglutaminase-mediated vimentin dimerization results in a novel unifying pathway by which vasodilatory and remodeling responses may be regulated. Ablation of vimentin expression inhibits migration and invasion of colon and breast cancer cell lines. Vimentin is the main intermediate filament protein in mesenchymal cells and is therefore of value in the differential diagnosis of undifferentiated neoplasms.
