Functioni

Involved in gene transcription regulation (PubMed:28106301, PubMed:21730289). Acts in concert with the corepressor URI1 to regulate androgen receptor AR-mediated transcription (PubMed:11854421, PubMed:21730289). Together with URI1, associates with chromatin to the NKX3-1 promoter region (PubMed:21730289). Negatively regulates the transcriptional activity of the estrogen receptor ESR1 by inducing its translocation into the cytoplasm (PubMed:28106301). May act as nuclear chaperone that facilitates the formation of the NF-kappa-B enhanceosome and thus positively regulates NF-kappa-B transcription activity (PubMed:17620405, PubMed:21307340). Potential component of mitochondrial-associated LRPPRC, a multidomain organizer that potentially integrates mitochondria and the microtubular cytoskeleton with chromosome remodeling (PubMed:17554592). Increasing concentrations of UXT contributes to progressive aggregation of mitochondria and cell death potentially through its association with LRPPRC (PubMed:17554592). Suppresses cell transformation and it might mediate this function by interaction and inhibition of the biological activity of cell proliferation and survival stimulatory factors like MECOM (PubMed:17635584).9 Publications

Interactioni

Subunit structurei

Homohexamer (PubMed:16221885). Interacts with LRPPRC (PubMed:11827465, PubMed:17554592). Interacts with androgen receptor AR (via N-terminus) (PubMed:11854421). Interacts with estrogen receptor ESR1; the interaction relocalizes ESR1 from the nucleus to the cytoplasm (PubMed:28106301). In the nucleus, interacts specifically with RELA (via RHD domain) and forms a dynamic complex with NF-kappa-B and is recruited to the NF-kappa-B enhanceosome upon stimulation (PubMed:17620405). Interacts with MECOM (PubMed:17635584). Interacts with URI1 (PubMed:21730289). Isoform 1 is part of complex I composed of TNF-alpha receptor TNFRSF1A, TRADD, TRAF2 and RIPK1 formed in response to TNF-alpha stimulation. Within the complex, interacts (via TPQE motif) with TRAF2; the interaction prevents the recruitment of FADD and CASP8/caspase 8 to complex I (PubMed:21307340).9 Publications
