Family relationships


MITF (microphthalmia-associated transcription factor) is a transcription factor that activates the transcription of melanocyte-specific genes [PMID: 8749302]. It is also involved in melanocyte differentiation, proliferation, and apoptosis [PMID: 15716956, PMID: 15623583, PMID: 17182868, PMID: 16899407, PMID: 18451137]. MITF has a basic-helix-loop-helix-leucine zipper (bHLHZip) structure; its leucine zipper appears to be essential for dimerisation and DNA binding [PMID: 7958932]. MITF also has important roles in osteoclast and mast cell development and function [PMID: 17105730, PMID: 16931285].

Mutations of the MITF gene are associated with Waardenburg syndrome type 2 (WS2) [PMID: 7874167, PMID: 8589691] and and albinism-deafness (Tietz) syndrome [PMID: 9546825].
