Multi-Directional Mechanisms of Participation of the Gene Family in Response of Innate Immune System to Bacterial Infections.

The multigene family is an important component of the innate immune system. For a long time, the main function of the genes belonging to this family was believed to be an antiviral defense of the host organism. The issue of their participation in the immune system response to bacterial invasion has been less studied.

Human TAF-Iα promotes oncogenic transformation via enhancement of cell proliferation and suppression of apoptosis.

Template activating factor-I (TAF-I) is a multifunctional protein involved in various biological processes including the inhibition of histone acetylation, DNA replication, cell cycle regulation, and oncogenesis. Two main TAF-I isoforms with different N-termini, TAF-Iα and TAF-Iβ (SET), are expressed in cells. There are numerous data about functional properties of TAF-Iβ, whereas the effects of TAF-Iα remain largely unexplored.

Human TRIM14 protects transgenic mice from influenza A viral infection without activation of other innate immunity pathways.

TRIM14 is an important component of innate immunity that defends organism from various viruses. It was shown that TRIM14 restricted influenza A virus (IAV) infection in cell cultures in an interferon-independent manner. However, it remained unclear whether TRIM14 affects IAV reproduction and immune system responses upon IAV infection in vivo.
