Endogenous retrovirus group K member 6 Rec protein (ERVK-6)

Retroviral replication requires the nuclear export and translation of unspliced, singly-spliced and multiply-spliced derivatives of the first genomic transcript. Rec interacts with a highly structured RNA element (RcRE) within the viral 3'LTR and recruits the cellular nuclear export machinery.

This permits export to the cytoplasm of unspliced genomic or incompletely spliced subgenomic viral transcripts. .
