TFEB is a member of the basic Helix-Loop-Helix-Zipper family of transcription factors. TFEB can bind DNA as a homodimer or as a heterodimer with three closely related family members: MITF, TFE3 and TFEC. The t(6;11)(p21;q12), a translocation recently been shown to result in fusion of Alpha, a gene on 11q12, with the transcription factor gene TFEB on 6p21.This translocation ultimately leads to the development of Renal carcinomas.
