EBV oncoprotein LMP1 transcriptionally induces TNFAIP2 expression via its CTAR2 domain through NF-κB (p65), acting on a newly identified NF-κB binding site at −3,869 to −3,860 bp of the TNFAIP2 promoter. TNFAIP2 then associates with actin and promotes formation of actin-based membrane protrusions and cell motility. |

TNFAIP2 directly binds the Kelch domain of KEAP1 via its DLG motif, competing with NRF2 for KEAP1 binding, thereby preventing NRF2 from undergoing ubiquitin-proteasome degradation and resulting in NRF2 accumulation that inhibits ROS-mediated JNK phosphorylation and confers cisplatin resistance. |

TNFAIP2 promotes CSF1R aggregate/cluster formation and dimerization in macrophages by binding cellular PIP2; the PIP2-binding motif on TNFAIP2 (and on CSF1R) is required for aggregate formation. TNFAIP2 also enhances CSF1R trafficking to the cell surface via RalA and the exocyst complex, increasing macrophage functional response to CSF-1. |

TNFAIP2 (M-Sec) is required for tunneling nanotube (TNT) formation in podocytes, enabling transfer of autophagosomes and lysosomes between cells; tnfaip2 knockout in mice exacerbates diabetic nephropathy, podocyte injury, and lysosomal dysfunction, demonstrating a protective role through TNT-mediated organelle exchange. |

Tnfaip2 acts epistatically upstream of vimentin (Vim) to control triacylglycerol (TAG) and lipid droplet synthesis; Tnfaip2-deficient embryonic stem cells fail to induce TAG and lipid droplet formation during differentiation, and supplementation with palmitic acid rescues the differentiation defect, establishing a role for Tnfaip2 in lipid metabolism-driven stem cell differentiation. |

TNFAIP2 translation is tightly suppressed by inhibitory upstream open reading frames (uORFs) in its transcript leader sequence; during monocyte-to-macrophage differentiation, these uORFs are inactivated, enabling a large increase in TNFAIP2 protein expression despite stable mRNA, revealing uORF-dependent translational control. |

TNFAIP2 inhibits NF-κB activity and downstream IL-8 production early in the TNFα response, acting as an autoinhibitor of TNFα signaling; a genetic variant (rs8126) that increases TNFAIP2 expression reduces IL-8 and is associated with decreased survival in septic shock. |
