The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/0.5 - 1/2. Detects a band of approximately 40-45 kDa (predicted molecular weight: 40 kDa).Can be blocked with Human TFEC peptide (ab22928).
Transcriptional regulator that acts as a repressor or an activator. Acts as a transcriptional repressor on minimal promoter containing element F (that includes an E-box sequence). Binds to element F in an E-box sequence-specific manner. Acts as a transcriptional transactivator on the proximal promoter region of the tartrate-resistant acid phosphatase (TRAP) E-box containing promoter (By similarity). Collaborates with MITF in target gene activation (By similarity). Acts as a transcriptional repressor on minimal promoter containing mu E3 enhancer sequence (By similarity). Binds to mu E3 DNA sequence of the immunoglobulin heavy-chain gene enhancer (By similarity). Binds DNA in a homo- or heterodimeric form.
Expressed moderately in spleen, kidney, bone marrow, small intestine and leukocytes. Expressed weakly in testis, trachea and colon.
Belongs to the MiT/TFE family. Contains 1 basic helix-loop-helix (bHLH) domain.
