Description générale
MiTF (Microphthalmia associated transcription factor) is a basic helix loop helix leucine zipper (b HLH ZIP) transcription factor implicated in pigmentation, mast cells and bone development. Mutations in MiTF cause auditory pigmentary syndromes, such as Waardenburg syndrome type II, type IIa and Tietz syndrome in humans. There are two known isoforms of MiTF differing by 66 amino acids at the NH2 terminus. Shorter forms are expressed in melanocytes and run as two bands at 52 kDa and 56 kDa, while 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. Mi is a basic helix-loop-helix-leucine zipper (b-HLH-ZIP) transcription factor implicated in pigmentation, mast cells and bone development. The mutation of Mi causes Waardenburg Syndrome type II in humans. In mice, a profound loss of pigmented cells in the skin eye and inner ear results, as well as osteopetrosis and defects in natural killer and mast cells. These melanocyte isoforms have been shown by two dimensional tryptic mapping to differ in c-Kit-induced phosphorylation. Osteopetrotic rat strain harbors a large genomic deletion encompassing the 3′ half of Mi including most of the b-HLH-ZIP region. Osteoclasts from these animals lack Mi protein in contrast to wild-type rat, mouse, and human osteoclasts.
Spécificité
In Western blotting, it recognizes a doublet of 52-56 kDa, identified as serine-phosphorylated and unphosphorylated forms of melanocytic isoforms of microphthalmia (Mi). There are two known isoforms of Mi differing by 66 amino acids at the NH2 terminus. Shorter forms are expressed in melanocytes and run as two bands at 52 kDa and 56 kDa, while 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 andheart. It reacts with both melanocytic as well as the nonmelanocytic isoforms of Mi. This Ab does not cross-react with other b-HLH-ZIP factors by DNA mobility shift assay.
Immunogène
Recombinant N-terminal fragment of human microphthalmia protein.
Application
Immunohistochemistry Analysis: A representative lot detected microphthalmia immunoreactivity in formalin-fixed, paraffin-embedded human metastatic melanoma tissue sections by fluorescent immunohistochemistry (Feige, E., et. al. (2011). Proc. Natl .Acad. Sci. U. S. A. 108(43):E924-E933).
Immunocytochemistry Analysis: A representative lot detected the exogenously expressed murine microphthalmia mutant constructs, Mitf D222/236N and Mitf D222N (mi-vit), in the nucleus of transfected COS-7 cells. Dual staining showed much reduced β-catenin-anchoring ability of these mutants in the nucleus (Schepsky, A., et al. (2006). Mol. Cell. Biol. 26(23): 8914-8927).
Immunocytochemistry Analysis: A representative lot detected a time-dependent induction of microphthalmia upregulation in B16/F10 murine melanoma cells upon Forskolin stimulation by fluorescent immunocytochemistry (Bertolotto, C., et al. (1998). J. Cell Biol. 142(3):827-835).
Electrophoretic Mobility Shift Assay (EMSA): A representative lot caused a supershift of Mbox motif oligonucleotide-complexed wild-type and D222/236N and D222N mutant murine microphthalmia constructs by EMSA (Schepsky, A., et al. (2006). Mol. Cell. Biol. 26(23): 8914-8927).
Electrophoretic Mobility Shift Assay (EMSA): A representative lot caused a supershift of Mbox motif oligonucleotide-complexed microphthalmia, but not TFE3-DNA complex by EMSA using in vitro translated microphthalmia and TFE3 or B16/F10 murine melanoma cell nuclear extract (Verastegui, C., et al.

Western Blotting Analysis: A representative lot detected a time-dependent induction of microphthalmia upregulation in B16/F10 murine melanoma cells and normal human melanocytes upon stimulation by Forskolin or α-melanocyte–stimulating hormone (αMSH) (Bertolotto, C., et al.

Transcription factors Mitf and NFATc1 share many downstream targets that are critical for osteoclastogenesis. Since RANKL signals induce/activate both NFATc1 and Mitf isoform-E (Mitf-E), a tissue-restricted Mitf isoform in osteoclasts, it is plausible that the two factors work together to
