Glycoproteins

Chitinase-3-like protein 1 (CHI3L1), also known as YKL-40, is a secreted glycoprotein that is approximately 40kDa in size that in humans is encoded by the CHI3L1 gene. The name YKL-40 is derived from the three N-terminal amino acids present on the secreted form and its molecular mass. YKL-40 is expressed and secreted by various cell-types including macrophages, chondrocytes, fibroblast-like synovial cells, vascular smooth muscle cells, and hepatic stellate cells. The biological function of YKL-40 is unclear. It is not known to have a specific receptor. Its pattern of expression is associated w

two groups of antibodies that are classified based on whether they bind to antigens or proteins directly or target another (primary) antibody that, in turn, is bound to an antigen or protein

A sequon is a sequence of consecutive amino acids in a protein that can serve as the attachment site to a polysaccharide, frequently an N-linked-Glycan. The polysaccharide is linked to the protein via the nitrogen atom in the side chain of asparagine (Asn). The sequon for N-glycosylation is either Asn-X-Ser or Asn-X-Thr, where X is any amino acid except proline, Ser denoting serine and Thr threonine. Occasionally, other amino acids can take the place of Ser and Thr, such as in the leukocyte surface protein (CD69), where the amino acid sequence Asn-X-Cys is an acceptable sequon for the addition

Draculin (named after Count Dracula) is a glycoprotein found in the saliva of vampire bats. It is a single-chain polypeptide protein composed of 708 amino acids, weighing about 88.5 kDa when reduced and 83 kDa when non-reduced, and selectively inhibits FIXa and FXa. It functions as an anticoagulant, inhibiting coagulation factors IX (IXa) and X (Xa) by establishing rapid equilibrium with factor Xa, and is the first natural polypeptide which has been described to show immediate anti-IXa and anti-Xa properties. In addition, Draculin inhibits the conversion of prothrombin to thrombin, preventing

Each patient has 6 electrophoresis panels: The left one is a conventional serum protein electrophoresis. The remainder get solutions with anti-IgG, anti-IgA, anti-IgM, anti-kappa light chain and anti-lambda light chain immunoglobulin, respectively from left to right. Each anti-immunoglobulin solution is artificially colored to ensure that the solution matches the color map at top. thumb|Immunofixation electrophoresis, schematic representation:- A.
