Transcriptional activator of the dopamine transporter (DAT), binding it’s promoter at the consensus sequence 5′-CCTGCACAGTTCACGGA-3′. Binds to 5′-d(GCC)(n)-3′ trinucleotide repeats in promoter regions and acts as a repressor of the FMR1 gene. Transcriptional repressor of MYC and thymidine kinase promoters.
