May act as an RNA-binding protein. The C-terminal region is highly homologous to the bornavirus nucleocapsid N protein that binds viral RNA and oligomerizes. The viral protein also possesses a nuclear import and a nuclear export signal. These 2 signals seem absent in EBLN-2 supporting an unrelated function in Human. Bornavirus is a non-retroviral RNA virus that does not generate DNA forms during viral replication. Therefore, integration of EBLN-2 must have occur through a mechanism relying on an endogenous reverse transcriptase activity.
