Activity summary

CD177 also known as neutrophil antigen NB1 is a glycoprotein with an approximate mass of 58 kDa. It is primarily expressed on the surface of neutrophils a type of white blood cell involved in immune response. The expression of CD177 can vary among individuals where some people might have a higher or lower presence on their neutrophils. CD177 has been identified to play a role in cell adhesion and signaling functions contributing to various cellular processes within the immune system.

Biological function summary

CD177 functions by mediating interactions between neutrophils and endothelial cells during inflammation. This protein is not known to be part of a multi-protein complex but it plays a significant role in facilitating neutrophil transmigration from blood vessels to sites of tissue damage or infection. This process supports the body's defense mechanisms by enabling neutrophils to quickly respond to external threats and participate in the inflammatory response.

Pathways

The involvement of CD177 in chemotactic activity and cell migration highlights its contribution to both the immune response and inflammation pathways. Its interaction with proteins such as PECAM-1 (Platelet Endothelial Cell Adhesion Molecule-1) enhances neutrophil transmigration across the endothelium. CD177 acts within these pathways to ensure a precise and rapid movement of neutrophils which is essential for an effective immune response.

Associated diseases and disorders

CD177 levels have associations with conditions like polycythemia vera and anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis. In polycythemia vera CD177 can affect the proliferation of blood cells due to its role in neutrophil function. In ANCA-associated vasculitis CD177's interaction with proteins such as PR3 (Proteinase 3) on the surface of neutrophils could contribute to the pathophysiology of the disease leading to inappropriate activation of the immune system and subsequent tissue damage.
