Macrosatellites are some of the largest variable number tandem repeats in the human genome, but what role these unusual sequences perform is unknown. Their importance to human health is clearly demonstrated by the 4q35 macrosatellite D4Z4 that is associated with the onset of the muscle degenerative disease facioscapulohumeral muscular dystrophy.(More)
For 25 mutant alleles of ret1, encoding the second largest subunit of yeast RNA polymerase III, we have studied the polymerase III nuclease activity, measuring both the total yield and dinucleotide product composition. Mutations affecting amino acids 309-325 gave slightly elevated nuclease activity. In region 367-376, two mutations gave 12-15-fold increased(More)
