Splicing of a human endogenous retrovirus to a novel phospholipase A2 related gene.

As part of an investigation into the effects of endogenous retroviruses on adjacent genes, we have isolated a cDNA clone derived from the human teratocarcinoma cell line NTera2D1 representing a chimeric transcript in which an endogenous retrovirus-like element, RTVL-H, has been spliced to downstream cellular sequences. The 5' terminus of this clone, termed AF-5, occurs one bp downstream of the predicted transcriptional start site in the RTVL-H long terminal repeat (LTR). AF-5 contains an open reading frame of 689 amino acids beginning within RTVL-H sequences that has two domains of homology with phospholipase A2 (PLA2).
