Depositor Comments

These plasmids consist of the L1RP element tagged with an enhanced green fluorescent protein (EGFP) cassette (pL1RP-EGFP) in a pCEP4 backbone (Invitrogen). The L1 element is driven by its 5′-UTR and an upstream CMV MIE promoter. L1-EGFP (EF06R, Addgene plasmid #42940) was derived from L1RP-EGFP by blunt ligation of 1–1392 nt of pPur (BD/Clontech) into the NruI site of pCEP4.

A negative control ‘dead’ L1-EGFP (EF05J, Addgene plasmid #42941) was similarly derived from pL1RP(JM111)-EGFP, which contains disabling mutations in ORF1.

An EN− plasmid (EF13E, Addgene plasmid #42942) was created by swapping 1927–3708 nt (Age I–Bcl I) from JM102D205A, which contains an endonuclease function-abrogating D205A point mutation in the EN domain, into EF06R.

A control plasmid (EF12J, Addgene plasmid #42943) was similarly derived from JM102. JM102 and JM102D205A are derived from L1.3, which differs from L1RP by 10 base changes in the region swapped.

I->T substitution at the end of ORF 2 should not affect plasmid function.
