What is Glycosylation?
Glycosylation refers to the enzymatic activity that attaches glycans (sugar molecules) to proteins or lipids. This change is central for protein folding, balance, and characteristic. There are two leading types of glycosylation: N-related and O-connected.
N-Linked Glycosylation
In N-connected glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This sort is widely used in many secreted and membrane-certain proteins.
O-Linked Glycosylation
O-connected glycosylation consists of attaching glycans to the hydroxyl team of serine or threonine residues. This kind is more commonly determined in mucins and other secreted proteins.
The Role of Glycoproteomics in Cancer Research
Glycoproteomics focuses on discovering the constructions and capabilities of glycoproteins. In melanoma research, it serves as a principal device for learning biomarkers that would cause early detection and higher healing systems.
Carbohydrate-Protein Interactions
