CER1 (DF0001369)

Internal part of retrotransposon CER1; gypsy/Ty3 group.

Description

LTRs of CER1 are named as LTRCER1. CDS 730..7548 /product="gag, pol and env protein precursor" A Gypsy/Ty3-class retrotransposon (Cer1) has 492 bp terminal repeats and one long (6819 nt) open reading frame. Alignment with other Gypsy-class elements and with retroviruses indicates that an env gene occupies the 3' 1.2 kb of the open reading frame. Since Gypsy of Drosophila has been shown to be an infectious element, it is possible that Gypsy-like elements are active in C. elegans.
