General description

Melan-A is also known as MART-1 (melanoma antigen recognized by T-cells 1). It is a transmembrane protein which is hydrophobic in nature. Melan-A is expressed in melanocytes and melanoma tumors.
Monoclonal Anti-Melan-A (mouse IgG1 isotype) is derived from the hybridoma A103 produced by the fusion of mouse myeloma cells (SP2/0 cells) and splenocytes from mice immunized with a human recombinant Melan-A protein. Melan-A (also known as MART1) is a melanoma antigen recognized by T cells. The protein is expressed mainly in cells and tumors of melanocytic lineage and thus belongs to the melanocyte differentiation markers.

Immunogen

recombinant human Melan-A protein.

Application

Anti-Melan-A antibody, Mouse monoclonal has been used in:
  • enzyme-linked immunosorbent assay (ELISA)
  • immunoblotting
  • immunocytochemistry
  • immunoprecipitation
  • immunohistochemistry

Biochem/physiol Actions

Melan-A/MART1 may have a role in pigmentation since its expression pattern and sub cellular distribution is similar to other melanosomal proteins and correlates with melanin content. Melan-A is important for Pmel17 activity, forms a complex with it, and affects its expression, stability, trafficking, and processing that is required for melanosome structure and maturation. Thus, Melan-A is important for Pmel17 function and therefore it is important for mammalian pigmentation.

Target description

Melan-A is a melanoma antigen recognized by T cells.

Physical form

Rationale: Tumor-associated fibroblasts (TAFs) play a critical role in the suppressive immune tumor microenvironment (TME), compromising the efficacy of immunotherapy. To overcome this therapeutic hurdle, we developed a nanoemulsion (NE) formulation to deliver fraxinellone (Frax), an anti-fibrotic medicine, to TAFs

Recent progress in the structural identification of human melanoma antigens recognized by autologous cytotoxic T cells has led to the recognition of a new melanocyte differentiation antigen, Melan-A(MART-1). To determine the properties of the Melan-A gene product, Melan-A recombinant protein
MART-1 is required for the function of the melanosomal matrix protein PMEL17/GP100 and the maturation of melanosomes.
