Gene Information
human ... LCN2(3934)
General description
Research area: Cell signaling. The gene LCN2 (lipocalin 2) is mapped to human chromosome 9q34. LCN2, a secreted glycoprotein, is an adipokine. It is expressed by many cells, such as respiratory and intestinal epithelial cells, endothelial cells, renal tubular cells, and cardiomyocytes. LCN2 belongs to the lipocalin family. LCN2 consists of the lipid binding domain that binds to small hydrophobic molecules and the ligand binding cavity that binds to bacterial and mammalian proteins called siderophores.
Application
LCN2 (lipocalin 2)-human has been used in the cell proliferation assay.It has also been used in conductometric immunoassay in renal carcinoma cells.
Biochem/physiol Actions
LCN2 (lipocalin 2) potentially connects obesity and its related adipose inflammation. LCN2 has also been implicated in a variety of processes including cell differentiation, tumorigenesis, and apoptosis. It is an early marker of acute kidney injury, cardiovascular diseases, lupus nephritis, and intestinal inflammation. LCN2 is upregulated in humans with heart failure. It can associate with MMP9 (matrix metalloproteinase-9) and controls its stability. Changes in the expression of LCN2 are associated with many cancers, including breast, colorectal, pancreatic, ovarian, gastric, thyroid, ovarian, bladder, and kidney cancers.LCN2 acts as a pleiotropicmolecule and plays a role in several pathophysiological and physiologicalactivities including immune response, inflammation, metabolic homeostasis, andinfection.
Physical form
Lyophilized with no additives.
Preparation Note
Centrifuge the vial prior to opening. Avoid freeze-thaw cycles.
