Updated project metadata. This project focuses on the functional characterization of a risk variant (SNP) implicated in the predisposition to uveal melanoma, rs452384. We sought to determine whether some nuclear factors could bind with allele-specificity a DNA sequence centered around rs452384 to regulate gene expression. We sought to identify by quantitative mass spectrometry the nuclear proteins bound to double-stranded DNA probes with identical DNA sequences except for rs452384-C or T alleles in the center of the probe. The goal was to quantify the binding of transcription factors to the DNA probes, and to select those enriched (or specific) to the C or T allele of rs452384. To identify proteins specifically bound to rs452384, we compared binding partners to those obtained with a negative control probe known not to recognize any transcription factor.
