Term Name:	Endogenous_Retrovirus_LTR_retrotransposon
Synonyms:	Endogenous Retrovirus LTR retrotransposon, HERV, RLE retrotransposon
Definition:	Endogenous retrovirus (ERV) retrotransposons are abundant in the genomes of jawed vertebrates. Human ERVs (HERVs) are classified based on their homologies to animal retroviruses. Class I families are similar in sequence to mammalian Gammaretroviruses (type C) and Epsilonretroviruses (Type E). Class II families show homology to mammalian Betaretroviruses (Type B) and Deltaretroviruses (Type D). F-Class III families are similar to foamy viruses.
