However, the evidence to support this is lacking: there are no MITF binding sites in the GLIPR1 promoter (not shown), and recent studies by others – although not taking epigenetic silencing into account – did not identify GLIPR1 as a direct target of either MITF or POU3F2 in melanoma cells (30–, 32). This evidence concerns the gene GLIPR1 and melanoma.
