The human genome carries multiple copies of sequences related to endogenous retroviral DNA. We report here the distribution of a new multicopy long terminal repeat (LTR) sequence that has been a part of an endogenous retrovirus-like sequence RTVL-H2. Twenty-four human chromosomes were either separated by flow sorting or by using rodent cells carrying a single human chromosome, and the DNA was subjected to Southern analyses using the RTVL-H2 DNA as a probe. The RTVL-H2 LTRs were distributed among all the human chromosomes, but the density and the profile differed from chromosome to chromosome. The same chromosome obtained from different individuals showed essentially the same chromosome-specific patterns. The distribution of the RTVL-H2 LTRs among different chromosomes did not correlate with the distribution of LTRs from another endogenous retroviral DNA, HERV-A, strongly suggesting that there is no preferred chromosome or a region thereof, for the integration. The possibility of rearrangement or amplification after integration is discussed.
