Cathepsin G also known as CTSG is a serine protease with a molecular mass of approximately 29 kDa. It is primarily located in azurophilic granules of neutrophils a type of white blood cell. Cathepsin G functions mechanically as an enzyme cleaving peptide bonds in proteins and shaping the protein components involved in various immune responses. Its enzymatic activity is important for host defense processes including bacterial degradation and immune cell signaling. Researchers easily measure and study 'G activity' using specific functional assays.
Biological function summary
Cathepsin G plays a significant role in the immune system by contributing to inflammatory responses and regulating cellular processes through its proteolytic activity. It participates in activating other proteins such as anti-bacterial serine enzymes and breaking down extracellular matrix components during immune response facilitation. While not part of a larger complex cathepsin G works alongside other proteases showing combinatory effects in innate immunity.
Pathways
Cathepsin G is involved in the immune and inflammatory pathways. It plays a part in the regulation of inflammatory responses and contributes to the activation of cytokines during infection and tissue injury. Cathepsin G connects through shared activity with other proteases like neutrophil elastase influencing processes in tissue remodeling and cytokine release. It sustains immune system homeostasis maintaining a balance between inflammation and tissue repair in these pathways.
Cathepsin G is linked to chronic inflammatory conditions and autoimmune disorders. For example rheumatoid arthritis showcases the enzyme's connection where cathepsin G contributes to tissue damage and joint inflammation. Cathepsin G's increased activity associates with neutrophil elastase aggravating symptoms of chronic obstructive pulmonary disease (COPD) as it contributes to lung tissue degradation. Understanding cathepsin G's role in these diseases aids research in therapeutic target development focusing on 'E-64d' inhibitors. These inhibitors reduce inflammatory damage by curbing excessive protease activity.
