Pglykoproteiini

Pglykoproteiini refers to a group of proteins that are glycosylated, meaning they have carbohydrate chains attached to them. These carbohydrate chains, known as glycans, can be attached either to the nitrogen atom of an asparagine residue (N-linked glycosylation) or to the oxygen atom of a serine or threonine residue (O-linked glycosylation). The process of adding these glycans to proteins occurs primarily in the endoplasmic reticulum and Golgi apparatus of eukaryotic cells.

The presence and structure of these glycans can significantly influence the protein's properties and functions. They play crucial roles in protein folding, stability, and solubility. Furthermore, glycans on the surface of cells can act as recognition sites for other molecules, mediating cell-cell interactions, immune responses, and the binding of pathogens. Many cell surface receptors and secreted proteins are glycoproteins.

Alterations in protein glycosylation patterns have been associated with various diseases, including cancer and inflammatory disorders. The study of glycoproteins, known as glycobiology, is a complex and vital field that seeks to understand the roles of these molecules in biological systems and their implications for health and disease. The term "Pglykoproteiini" is a Finnish term for glycoprotein.
