Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting,

Specificity / Sensitivity

TFE3 Antibody recognizes endogenous levels of total TFE3 protein. The upper band is presumed to be sumoylated TFE3 protein. This antibody does not cross react with the closely related MITF protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human TFE3 protein. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using TFE3 Antibody.


Transcription factor E3 (TFE3) is a member of a family of basic helix-loop-helix leucine zipper transcription factors that includes MITF, TFEB, TFE3, and TFEC. Members of this family form heterodimers with each other, bind the same DNA sequences, and undergo the same types of post-translational modifications, including sumoylation (1). Research studies indicate that TFE3 and other family members play roles in development, organelle biogenesis, nutrient sensing, autophagy, and energy metabolism (2,3). Additional studies report that TFE3 controls the gate for pluripotent cells to exit the state of pluripotency prior to differentiation (4). Translocations involving the TFE3 gene region have been identified in a number of tumors, including sporadic renal cell tumors. Several specific translocations that result in kidney cancer and involve the TFE3 gene have been described and characterized in detail (5).
