Transcription factor 3
E12, E2A, E47, Transcription Factor-3
This gene encodes a member of the E protein (class I) family of helix-loop-helix transcription factors. E proteins activate transcription by binding to regulatory E-box sequences on target genes as heterodimers or homodimers, and are inhibited by heterodimerization with inhibitor of DNA-binding (class IV) helix-loop-helix proteins. E proteins play a critical role in lymphopoiesis, and the encoded protein is required for B and T lymphocyte development. Deletion of this gene or diminished activity of the encoded protein may play a role in lymphoid malignancies. This gene is also involved in several chromosomal translocations that are associated with lymphoid malignancies including pre-B-cell acute lymphoblastic leukemia (t(1;19), with PBX1), childhood leukemia (t(19;19), with TFPT) and acute leukemia (t(12;19), with ZNF384). Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and a pseudogene of this gene is located on the short arm of chromosome 9.

OBJECTIVE: To investigate the clinical characteristics of E2A-PBX1（immunoglobulin enhancer binding factor-pre-B leukemia）fusion gene in patients with acute lymphoblastic leukemia（ALL） after allogeneic stem cell transplantation（allo-HSCT）.

The changes observed in xenografts were associated with decreased PPARβ/δ-dependent expression of proliferating cell nuclear antigen and octamer-binding transcription factor-3/4, suggesting suppressed tumor proliferation and induction of differentiation.
This study performed analysis of the CDKN2 deletion in 215 adult B- lineage acute lymphoblastic leukemia (B-ALL) patients, and related cytogenetic prognostic factors (BCR/ABL; E2A/PBXl; TEL/AML1; Mixed Lineage Leukemia (MLL) rearrangement; MYC, Immunoglobulin heavy locus (IGH) translocation).
We developed novel Ad vectors by incorporating targeted sequences of miR-122a or miR-142-3p, which exhibit liver- or spleen-specific expression, respectively, in the 3'-untranslated region (UTR) of the E2A, E4, or pIX genes.

Structured interaction matrix analysis showed that occupancy by the architectural protein CTCF was associated mainly with intradomain interactions, whereas sites bound by the histone acetyltransferase p300 or the transcription factors E2A or PU.1 were associated with intra- and interdomain interactions that are developmentally regulated.

Deficiency in the E proteins, E2A and HEB, led to increased frequency of terminally differentiated effector KLRG1(hi) CD8(+) T cells in mice during infection, and decreased generation of longer-lived memory-precursor cells during the immune response.
