  • Target

    • Function

      Transcription factor that specifically recognizes and binds E-box sequences (3'-CANNTG-5'). Efficient DNA-binding requires dimerization with itself or with another MiT/TFE family member such as TFEB or MITF. In association with TFEB, activates the expression of CD40L in T-cells, thereby playing a role in T-cell-dependent antibody responses in activated CD4(+) T-cells and thymus-dependent humoral immunity. Specifically recognizes the MUE3 box, a subset of E-boxes, present in the immunoglobulin enhancer. It also binds very well to a USF/MLTF site.
    • Tissue specificity

      Ubiquitous in fetal and adult tissues.
    • Involvement in disease

      Note=A chromosomal aberration involving TFE3 is found in patients with alveolar soft part sarcoma. Translocation t(X;17)(p11;q25) with ASPSCR1 forms a ASPSCR1-TFE3 fusion protein.
      Note=Chromosomal aberrations involving TFE3 are found in patients with papillary renal cell carcinoma. Translocation t(X;1)(p11.2;q21.2) with PRCC; translocation t(X;1)(p11.2;p34) with PSF; inversion inv(X)(p11.2;q12) that fuses NONO to TFE3.
    • Sequence similarities

      Belongs to the MiT/TFE family.
      Contains 1 basic helix-loop-helix (bHLH) domain.
    • Post-translational

      Sumoylated; does not affect dimerization with MITF.
    • Cellular localization

    • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of Human testis tissue sections labeling TFE3 with Purified ab179804 at 1:100 dilution (6.59 μg/ml). Heat mediated antigen retrieval was performed using citrate Buffer, pH6.0. Tissue was counterstained with Hematoxylin. ImmunoHistoProbe one step HRP Polymer (ready to use) secondary antibody was used at 1:0 dilution. PBS instead of the primary antibody was used as the negative control.

    • Immunohistochemical analysis of paraffin-embedded Human thyroid gland carcinoma tissue labeling TFE3 with unpurified ab179804 at 1/250 dilution.

    • Immunohistochemical analysis of paraffin-embedded Human renal cell carcinoma tissue labeling TFE3 with unpurified ab179804 at 1/250 dilution.
