TFE3 Transcription factor that specifically recognizes and binds E-box sequences (5'-CANNTG-3'). 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. May regulate lysosomal positioning in response to nutrient deprivation by promoting the expression of PIP4P1. Belongs to the MiT/TFE family. Ubiquitous in fetal and adult tissues. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
