Vimentin antibody

Vimentin, a member of the intermediate filament (IF) family, is a protein responsible for maintaining cellular integrity and reducing damage caused by stress.

Vimentin is a fundamental 10 nm type III intermediate filament (IF) protein found in many mesenchymal and epithelia tissues, tissue culture cells, and developing neuronal and astrocytic precursor cells of the central nervous system.

Epithelial-to-mesenchymal transition (EMT) is a critical event in the induction of cell motility and increased survival both under physiological situations like wound healing or development, as well as in malignant cells undergoing invasion and metastasis. Vimentin is an intermediate filament protein which is characteristically upregulated in cells undergoing EMT. Recent studies support the notion that vimentin functions as a positive regulator of EMT and upregulation of vimentin appears to be a prerequisite for EMT induction (1).

Vimentin is a 57kDa type III intermediate filament (IF) protein that is the major cytoskeletal component of mesenchymal cells and the first to be expressed during cell differentiation. It plays a significant role in supporting and anchoring the position of the organelles in the cytosol and its dynamic nature is important for cell flexibility.  It is responsible for maintaining cell shape and cytoplasm integrity.

ZMPSTE24 (FACE-1, CAAX prenyl protease 1 homolog) is a membrane associated zinc metalloprotease of the peptidase M48A family. It's catalytic activity can be defined as the peptide bond hydrolyzed in the sequence -C-|-A-A-X in which C is an S-isoprenylated cysteine residue, A is usually aliphatic and X is the C-terminal residue of the substrate protein, and may be any of several amino acids. It has been shown to specifically cleave the final 3 carboxy terminal residues from farnesylated prelamin A to form mature lamin A.
