  • 1

    TIFA is an adaptor protein that mediates innate immune signaling through phosphorylation-dependent oligomerization and TRAF6 activation.

  • 2

    The ALPK1-TIFA signaling pathway links microbial metabolite sensing to immune response initiation.

  • 3

    TIFA exhibits dual roles as an oncogenic factor in some contexts and a tumor suppressor in others.

  • 4

    TIFA's FHA domain enables specific recognition of phosphorylated motifs, facilitating protein-protein interactions.

  • 5

    TIFA oligomerization enhances TRAF6-mediated NF-κB activation, amplifying inflammatory signaling pathways.
