Fc gamma RIIIA/CD16a Protein, Rat (HEK293, His)

Fc γ RIIIA/CD16a is a receptor for the invariant Fc fragment of immunoglobulin γ (IgG). Fc γ RIIIA/CD16a regulates NK cell survival and proliferation and prevents NK cell progenitor cell apoptosis. Fc γ RIIIA/CD16a plays a role in mediating the anti-tumor activity of therapeutic antibodies by triggering TNFA-dependent ADCC, which promotes the entry of the virus into bone marrow cells during secondary infection and subsequent viral replication through antibody-dependent enhancement (ADE). Fc gamma RIIIA/CD16a Protein, Rat (HEK293, His) is the recombinant rat-derived Fc gamma RIIIA/CD16a protein, expressed by HEK293 , with C-His labeled tag. The total length of Fc gamma RIIIA/CD16a Protein, Rat (HEK293, His) is 179 a.a., with molecular weight of 28-33 kDa.

The Fc γ RIIIA/CD16a protein is a receptor for the invariant Fc fragment of immunoglobulin γ (IgG) and is optimally activated upon binding to the aggregation antigen-igg complex displayed on the cell surface, initiating antibody-dependent cytotoxicity (ADCC). Fc γ RIIIA/CD16a mediates IgG effects on natural killer (NK) cells, binding to antigen-igg complexes produced during infection, triggering NK cell-dependent cytokine production and degranulation. Fc γ RIIIA/CD16a plays a crucial role in the generation of memory-like adaptive NK cells, regulating NK cell survival and proliferation, and preventing NK cell progenitor cell apoptosis. Fc γ RIIIA/CD16a plays a role in mediating the antitumor activity of therapeutic antibodies, triggering TNFA-dependent ADCC in IgG-coated tumor cells and enhancing ADCC in response to focused IgG. Fc γ RIIIA/CD16a is involved in pathogenesis through an antibody-dependent enhancement (ADE) mechanism that promotes the entry of the virus into bone marrow cells during secondary infection and subsequent viral replication^[1][2][3].
