Anti-MiTF Antibody, clone 3D1.2

Microphthalmia-associated transcription factor (MiTF) is a basic helix loop helix leucine zipper (b HLH ZIP) transcription factor implicated in pigmentation, and development of mast cells and bone. Mutations in MiTF cause auditory pigmentary syndromes in humans, such as Waardenburg syndrome type II and type IIa, and Tietz syndrome. There are two known isoforms of MiTF, differing by 66 amino acids at the N-terminus. Shorter forms are expressed in melanocytes and run as two bands at 52 kDa and 56 kDa, whereas the longer Mi form runs as a cluster of bands at 60-70 kDa in osteoclasts and in B16 melonoma cells (but not other melanoma cell lines), as well as mast cells and heart. MiTF plays a critical role in the differentiation of various cell types as neural crest-derived melanocytes, mast cells, osteoclasts and optic cup-derived retinal pigment epithelium.

~52 kDa observed. Multiple isoforms between 46-56 kDa are known to exist.
