TRIM21 is a high-affinity antibody receptor uniquely expressed in the cytosol of mammalian cells. Here we summarize its role in extending antibody protection into the intracellular environment and allowing nonprofessional cells to benefit from adaptive immunity. We highlight recent work that has shed light on how TRIM21 acts as both an immune sensor and effector. We also review how TRIM21 synergizes with other innate immune receptors to promote an integrated antiviral response.
