Abstract: Avian leukemia virus E subgroup (ALV-E) is an endogenous retroviral element integrated in chicken genome. In recent years, many new ALVEs have been described with the develop-ment of genome sequencing projects. However, the ALV-E effects on host have not been fully understood. In this review, the structure and function of ALV-E were summarized, and the regu-lation of transcription initiation activity of ALV-E was elaborated, and the structure characteristics of ALV-E location in host genome was expounded. Finally, the effects of ALV-E on host function was discussed, which would provide reference for further understanding the function and expression regulation mechanism of avian leukemia virus in the genome of host.

Key words: endogenous retrovirus, biosynthesis, transcriptional regulation, biological function
