This protein functions as a needle component playing a mechanical role in piercing host cell membranes to deliver bacterial effectors directly into host cells. PrgI is a small protein with an estimated mass of around 9.6 kDa. Typically PrgI is expressed in pathogenic bacteria where T3SS is active which includes various specialized cells involved in infection.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nPrgI facilitates the translocation of virulence factors from the bacterial cytoplasm to host cell cytosol. PrgI forms a part of the needle complex a large structure spanning both bacterial membranes. The needle complex works together with other proteins such as PrgH and PrgK to ensure the successful injection of effector proteins into host cells. This protein assembly allows the bacterium to manipulate host cell functions aiding bacterial survival and replication within the host.\u003cbr\u003e\nPathways\u003cbr\u003e\nPrgI integrates into the pathogenicity pathways of bacteria like Salmonella. It plays a significant role in the Salmonella pathogenicity island 1 (SPI-1) pathway which is important for enabling bacterial invasion into non-phagocytic cells. In this context PrgI works closely with other T3SS components such as InvG and SicA to mediate effector protein translocation and establish infection. Understanding PrgI's role highlights its importance in the formation and regulation of secretion systems that contribute to bacterial pathogenicity.\u003cbr\u003e\nPrgI strongly connects to foodborne illnesses caused by Salmonella infections. Such infections can lead to gastroenteritis and more severe systemic diseases like typhoid fever. PrgI's interactions with proteins like SipA and SipC amplify its role in promoting bacterial virulence and disease progression. Research into PrgI not only aids in comprehending these bacterial infections but also provides opportunities to develop interventions that disrupt its function potentially reducing the disease burden stemming from Salmonella and related pathogens.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843897774249,"sku":"ab237560","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab237560","provider":"Iright","version":"1.0","type":"link"}
