The objective of this project is to analyze the functional role of the mutations p.Cis65Tir, p.Arg39Cis, p.Ser32Asn and p.Cis247* in NR5A1 protein, as well as the effect of nucleotide variations (c.-133G>A, c.-156_-136ins18pb, c.-413G>A, c.-208C>A, and c.-762C>T) identified in NR5A1 5'UTR and exon 1, which are non-coding regions but are important for NR5A1 transcriptional regulation. This investigation will focus in the ability Sp1 protein binding since those nucleotide variations localize in putative Sp1 binding sites. The methodology for the study will include: cloning and expression of normal and mutants NR5A1 gene, electrophoretic mobility sift and supershift assays (EMSA), Western Blotting, expression of gene reporter assays using luciferase as marker and two-hybrid system assays.
