Melanocyte-specific microphthalmia-associated transcription factor isoform activates its own gene promoter through physical interaction with lymphoid-enhancing factor 1.

Abstract excerpt

Waardenburg syndrome type 2 (WS2) is associated with heterozygous mutations in the gene encoding microphthalmia-associated transcription factor (MITF) and characterized by deafness and hypopigmentation due to lack of melanocytes in the inner ear and skin. Melanocyte-specific MITF isoform (MITF-M) is essential for melanocyte differentiation and is transcriptionally induced by Wnt signaling that is mediated by...
