It is found in the cell wall of the bacterium Staphylococcus aureus. This protein binds strongly to immunoglobulins especially the Fc region of IgG making it a useful tool in biochemical research. This binding property is used to isolate antibodies and also in various immunoassays such as Protein A ELISA kits.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nProtein A from Staphylococcus aureus plays a role in the evasion of host immune responses. It helps the bacterium avoid detection by immune cells aiding in its pathogenicity. Protein A does not form part of any large complex but interacts directly with IgG molecules. This ability to bind antibodies is leveraged in the laboratory to purify antibody-antigen complexes which can be critical for research and diagnostic applications.\u003cbr\u003e\nPathways\u003cbr\u003e\nIts role is more mechanical than part of any classic biochemical pathways but it contributes to evasion of the host immune pathway. It has connections with immune signaling proteins such as the Fc receptors found on immune cells. The interception and binding of antibodies by Protein A can modulate the normal immune signaling pathways thereby impacting immune surveillance and response.\u003cbr\u003e\nProtein A's interaction with the immune system links it to conditions involving Staphylococcus aureus infections such as pneumonia and skin infections. Its ability to interfere with antibody function contributes to the virulence of Staphylococcus aureus and complicates the immune response. Its connection to Fc receptor proteins illustrates its potential role in evading immune reactions during the infectious disease process presenting challenges in treatment and diagnosis.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46855507050665,"sku":"ab18598","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab18598","provider":"Iright","version":"1.0","type":"link"}
