Protein Function and Prediction

Elf3 encodes an E26 transformation-specific (ETS) transcription factor.  The Ets transcription factors are often mediators of extracellular signaling pathways that regulate cell proliferation, differentiation, apoptosis, and cell-cell/cell-matrix interactions (1;2).  Elf3 is involved in embryonic epithelial differentiation (3). Elf3 controls intestinal epithelial differentiation during development by regulating the expression of TGFβRII in epithelial cells [(4;5); reviewed in (6)]. Elf3 is also involved in mediating vascular inflammation after induction by inflammatory cytokines and lipopolysaccharide in vascular smooth muscle cells, endothelial cells, and cells of the monocyte-macrophage lineage; induction is mediated by by NF-κB transactivation of the Elf3 promoter. Elf3 can bind to the p50 subunit of NF-κB, an ESE-1-binding site within the NOS2 promoter has been identified, and Elf3 is also a transcriptional mediator of angiopoietin-1 in inflammation (7;8).  In addition, Elf3 regulates allergic airway inflammation by regulating DC-driven T cell differentiation (9). Other proposed roles of Elf3 are terminal differentiation of the epidermal skin epithelium, mammary gland development and breast cancer, and lung development, regeneration, and cancer [reviewed in (10)].


Elf3 is highly expressed in epithelial-rich tissues such as stomach, small intestine, colon, pancreas, trachea, lung, kidney, salivary gland, prostate gland, mammary gland, uterus, and skin (11;12).


Elf3tm1Pjh/tm1Pjh; MGI:2662485

involves: 129S4/SvJae * C57BL/6

About one third of mice homozygous for a reporter allele die at E11.5; over half of those born develop a wasted phenotype, lethargy and watery diarrhea and die during the first few weeks of life exhibiting dysmorphogenesis and altered differentiation of small intestinal epithelium (3).  The impaired enterocyte and goblet cell differentiation can be rescued by transgenic TGFβRII expression in the intestinal epithelium (4) via direct stimulation of TGFβRII promotor activity (5).


Elf3−/− mice: not clear if same model as above; not indicated in publication

Elf3−/− mice were impaired in Th17 induction after epicutaneous sensitization and airway challenge with OVA (9). After epicutaneous sensitization, Elf3−/− mice have impaired Th1 differentiation, which subsequently promotes Th2 differentiation (9).  IL-6 production in the OVA-challenged and -sensitized Elf3−/− mice is impaired (9).  These mice exhibit increased maturation and migration of dendritic cells upon OVA sensitization (9).
