The protein has a molecular mass of around 120 kilodaltons. Mechanically gp120 plays a critical role in HIV's ability to infect host cells. It binds to the CD4 receptor on host T-cells and other immune cells. This interaction facilitates the fusion of the viral envelope with the host cell membrane allowing viral entry and subsequent infection.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nGp120 is essential for viral recognition and binding to the host's immune cells. It is a part of the larger HIV envelope glycoprotein complex along with gp41 forming a trimeric unit that is pivotal for the virus's function. gp120's ability to interact with both the CD4 receptor and co-receptors like CCR5 or CXCR4 defines the tropism of the virus for specific cell types. This targeting mechanism enhances the virus's ability to evade the immune system contributing to the persistence of infection.\u003cbr\u003e\nPathways\u003cbr\u003e\nGp120 is heavily involved in the entry pathway of the HIV virus into host cells. The primary pathway includes attachment to the CD4 receptor followed by interaction with a coreceptor commonly CCR5 or CXCR4 leading to fusion and viral entry. These interactions are critical in the HIV infection cycle and are targeted by therapeutic interventions. Additionally the involvement of gp41 in the envelop complex is important for the fusion process working closely with gp120.\u003cbr\u003e\nGp120 is directly linked to HIV and its pathogenesis in causing Acquired Immunodeficiency Syndrome (AIDS). It facilitates the initial viral entry that leads to the systemic infection associated with the disease. The interaction between gp120 and CD4 receptors plays a significant role in the decline of T-cell populations a hallmark of AIDS. Furthermore gp120's relationship with CCR5 co-receptor also connects it to conditions involving CCR5 such as CCR5-tropic HIV infections guiding therapeutic strategies that aim to block these interactions.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843984511145,"sku":"ab174070","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab174070","provider":"Iright","version":"1.0","type":"link"}
