Microphthalmia-associated bHLH-LZ transcription factor (MITF) is a positively acting transcription factor containing a transcription activation domain and a bHLH-LZ domain that mediates DNA-binding and dimerization. Both the transcription activation and bHLH-LZ domains are highly conserved in the closely related TFE3, TFEB and TFEC. MITF can form heterodimers in vitro with the above transcription factors, but not with other bHLH-LZ factors such as Myc, Max or USF. MITF is expressed as multiple isoforms, which share common activation and DNA-binding domains, but differ in the amino-terminal region. MITF is targeted by three kinases: GSK-3beta, Map kinase ERK2 and members of the p90 Rsk family of kinases.
