Novel families of interspersed repetitive elements from the human genome.
Six novel families of interspersed repetitive elements have been detected in the available human DNA sequences using computer-assisted analyses. The estimated total number of elements in the reported six families is over 17,000. Sequences representative for each family range from approximately 150 to 650 base pairs (bp) in length and are predominantly (A + T)-rich. Sequences from four families contain stretches of patchy complementarity up to 45 bp long. Member of one of the families is likely be directly involved in a multigene deletion on chromosome 14. Two of the six sequence families are homologous to 'low reiteration frequency sequences' from monkey cells, detected first in defective variants of simian virus 40. Like Alu and L1 families, the newly discovered families are probably composed of pseudogenes derived from functional genes.
