TRIM11 was identified as a binding partner of the neuroprotective peptide Humanin (HN). The interaction requires both the coiled-coil and B30.2 domains of TRIM11. TRIM11 reduces intracellular HN levels via ubiquitin-mediated proteasomal degradation; disruption of the RING finger domain or proteasome inhibition significantly diminished this effect. |

Trim11 interacts with the transcription factor Pax6 via its B30.2 domain and mediates Pax6 degradation through the ubiquitin-proteasome system. Trim11 overexpression decreases endogenous Pax6 protein, represses Pax6-dependent transactivation and neurogenesis, and knockdown of Trim11 increases insoluble Pax6 and enhances apoptosis. The B30.2 domain of Trim11 is essential for clearance of insoluble Pax6. Pax6 also directly regulates Trim11 transcription, forming an autoregulatory feedback loop. |

TRIM11 regulates SUMO1 modification of 0N4R-tau. TRIM11 (previously identified as an E3 SUMO2 ligase for tau) was found to also increase SUMO1 modification of both 2N4R- and 0N4R-tau; mutation of the target lysine residue to arginine attenuated this effect. SUMO1 modification increased phosphorylated tau levels, which was suppressed by SENP1. |

TRIM11 and JAK1 interact and mutually regulate each other via post-translational modifications in response to IFN-γ. JAK1 phosphorylates TRIM11, stabilizing it by reducing K48-linked polyubiquitination. In turn, TRIM11 promotes K63-linked polyubiquitination of JAK1, inhibiting downstream JAK/STAT signaling and reducing IFN-γ-induced PD-L1 expression. This enhances cytotoxic T lymphocyte (CTL) activity and anti-tumor immunity. |
