General description

Microphthalmia (Mi in mouse or MITF in human) is a basic helix-loop-helix-leucine zipper (BHLH–ZIP) transcription factor involved in the differentiation, development and survival of melanocytes and cells of the retinal pigment epithelium, i.e. cells responsible for hair, skin, and eye color. It activates the expression of the melanocyte specific genes tyrosinase and TRP1 (tyrosinase-related protein 1) by binding as a homo- or heterodimer to a symmetrical DNA sequence (E box) (5′-CATGTG-3′) located within the M box found in their promoters. Microphthalmia also appears to be involved in the differentiation of mast cells, osteoclasts, basophils and natural killer cells.
Microphthalmia is expressed in a limited number of cell types including heart, mast cells, osteoclast precursors, and melanocytes. There are a number of different isoforms of microphthalmia resulting from alternative splicing and alternative promotors. These isoforms differ at their amino-termini and in their expression patterns.
Mouse monoclonal clone C5 anti-Microphthalmia antibody recognizes serine phosphorylated and non-phosphorylated melanocytic isoforms of microphthalmia from human, mouse or rat.

Immunogen

N-terminal fragment of human microphthalmia protein.

Application

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Western Blotting (1 paper)
Mouse monoclonal clone C5 anti-Microphthalmia antibody is used to tag serine phosphorylated and non-phosphorylated melanocytic isoforms of microphthalmia for detection and quantitation by techniques such as immunoblotting (doublet of 52-56 kDa), immunoprecipitation, immunohistochemistry on formalin-fixed paraffin embedded or frozen tissue sections, and gel shift. It is used as a probe to determine the roles of microphthalmia in the differentiation, development and survival of melanocytes and cells of the retinal pigment epithelium.

Physical form

Solution in phosphate buffered saline containing 0.08% sodium azide.

The profound but frequently transient clinical responses to BRAFV600 inhibitor (BRAFi) treatment in melanoma emphasize the need for combinatorial therapies. Multiple clinical trials combining BRAFi and immunotherapy are under way to further enhance therapeutic responses. However, to which extent BRAFV600

Induced pluripotent stem cells (iPSCs) are a promising melanocyte source as they propagate indefinitely and can be established from patients. However, the in vivo functions of human iPSC-derived melanocytes (hiMels) remain unknown. Here, we generated hiMels from vitiligo patients using a three-dimensional
