SST1 (DF0001065)

SST1 - large human satellite identified with SstI enzyme


SST1 represents ~1.5Kb of a ~2.5Kb tandemly repeating satellite found on human chromosomes 19 and 4, far from the centromere or telomere. When found outside of these chromosomes, they tend to be centromeric. A subsegment of SST1 can also be found at several sites in human at one terminus of a GSATII gamma satellite array.
