Description
General description
The protein named Transcription factor EB (TFEB) or alternatively in older literature, Class E basic helix-loop-helix protein 35 (bHLHe35) and encoded by the human gene TFEB/BHLH35 is a transcription factor that specifically recognizes and binds E-box sequences (5′-CANNTG-3′) on DNA. Efficient DNA-binding requires dimerization with itself or with another MiT/TFE family member such as TFE3 or MITF. TFEB in association with the protein 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. TFEB also plays a central role in expression of lysosomal genes. TFEB specifically recognizes and binds the CLEAR-box sequence (5′-GTCACGTGAC-3′) present in the regulatory region of many lysosomal genes and through binding acts as a positive regulator of their expression. Finally, TFEB appears to be a positive regulator for autophagy related gene expression, heavy chain immunoglobulin gene expression, and genes necessary for the proper vascularization of important tissues such as the placenta.
~58 kDa and ~40 kDa observed. Uniprot describes two isoforms at 44 kDa and 53 kDa This protein has been observed at 44-53 kDa due to sumoylation (Miller, A. J., et al. (2005). J Biol Chem. 280(1):146-55.).
