Microphthalmia-associated transcription factor (MITF), a basic helixloop- helix ( bHLH) transcription factor with a leucine zipper. This is a key protein in regulation of the melanin biosynthesis in melanocytes. For the transcription initiation of the mRNAs responsible for translation of melanogenesis associated proteins, the binding of the MITF to E-box is required. The goal of this study is to evaluate the interaction of MITF with respective DNA binding site (E-box, CATGTG) by surface plasmon resonance (SPR). A Label-free gold chip based DNA-protein interaction assay, being used to evaluate the interactions. The MITF showed almost a twice higher resonance signal after binding with E-box, when compared to mutated E-Box. We have also assessed various parameters to stabilize the assay conditions, to diminish the false signals. We expect that evaluation of interaction provide a quantitative, comparative, high-throughput screening of MITF inhibitors, which will help to develop an effective methodology of screening of potential depigmenting agent.
