  • 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 TFE3 or MITF. In association with TFE3, 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 and binds the CLEAR-box sequence (5'-GTCACGTGAC-3') present in the regulatory region of many lysosomal genes, leading to activate their expression. It thereby plays a central role in expression of lysosomal genes. Specifically recognizes the gamma-E3 box, a subset of E-boxes, present in the heavy-chain immunoglobulin enhancer. Plays a role in the signal transduction processes required for normal vascularization of the placenta.
    • Sequence similarities

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

      The leucin zipper region is essential for homo- or heterodimerization and high-affinity DNA binding. DNA binding is mediated by the basic region.
    • Post-translational

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

      Cytoplasm. Nucleus. Mainly present in the cytoplasm. Under aberrant lysosomal storage conditions, it translocates from the cytoplasm to the nucleus.

    I see that you mentioned in the additional notes that there was a very faint band at 43kDa. I just wanted to inform you that the expected band size for TFEB is 53kDa. Did you see a positive band around the 53dDa size?
    I am sorry to hear that you have been experiencing issues when using this antibody. This product is covered by our Abpromise guarantee. According to Abpromise guarantee, if this product has been purchased within the last six months, we are happy to provide scientific support and to replace or refund the product should we not be able to help.
    Upon initial review of your protocol, I have a few recommendations to potentially reduce the number of non-specific bands you are seeing:
    1. Increase the blocking time
    2. Include protease and phosphatase inhibitors (TFEB is undergoes post-translational phosphorylation)
    Further troubleshooting tips are given through the link below:
