Functioni

Multifunctional transcription factor in ER stress response. Plays an essential role in the response to a wide variety of cell stresses and induces cell cycle arrest and apoptosis in response to ER stress. Plays a dual role both as an inhibitor of CCAAT/enhancer-binding protein (C/EBP) function and as an activator of other genes. Acts as a dominant-negative regulator of C/EBP-induced transcription: dimerizes with members of the C/EBP family, impairs their association with C/EBP binding sites in the promoter regions, and inhibits the expression of C/EBP regulated genes. Positively regulates the transcription of TRIB3, IL6, IL8, IL23, TNFRSF10B/DR5, PPP1R15A/GADD34, BBC3/PUMA, BCL2L11/BIM and ERO1L. Negatively regulates; expression of BCL2 and MYOD1, ATF4-dependent transcriptional activation of asparagine synthetase (ASNS), CEBPA-dependent transcriptional activation of hepcidin (HAMP) and CEBPB-mediated expression of peroxisome proliferator-activated receptor gamma (PPARG). Inhibits the canonical Wnt signaling pathway by binding to TCF7L2/TCF4, impairing its DNA-binding properties and repressing its transcriptional activity. Plays a regulatory role in the inflammatory response through the induction of caspase-11 (CASP4/CASP11) which induces the activation of caspase-1 (CASP1) and both these caspases increase the activation of pro-IL1B to mature IL1B which is involved in the inflammatory response.9 Publications

Involvement in diseasei

Myxoid liposarcoma (MXLIPO)1 Publication
The gene represented in this entry may be involved in disease pathogenesis. A chromosomal aberration involving DDIT3 has been found in a patient with malignant myxoid liposarcoma. Translocation t(12;16)(q13;p11) with FUS (PubMed:7503811).1 Publication
Disease descriptionA soft tissue tumor that tends to occur in the limbs (especially the thigh) of patients ranging in age from 35 to 55 years. It is defined by the presence of a hypocellular spindle cell proliferation set in a myxoid background, often with mucin pooling. Lipoblasts tend to be small and often monovacuolated and to cluster around vessels or at the periphery of the lesion.
