May act as an RNA-binding protein. Highly homologous to the bornavirus nucleocapsid N protein that binds viral RNA and oligomerizes (By similarity). Expression detected by RT-PCR in a few cell lines, including OL, HEK293T and MOLT-4. Not observed in HeLa cells (PubMed:20054395). Bornavirus is a non-retroviral RNA virus that does not generate DNA forms during viral replication. Therefore, integration of EBLN-1 must have occur through a mechanism relying on an endogenous reverse transcriptase activity.
