Latency I (Lat I), identified in Burkitt lymphoma (BL) biopsies and many derived BL cell lines (Rowe et al., 1992), is characterized by a lack of Cp/Wp promoter activity and the expression of a single latent antigen EBNA1 from the alternate Qp promoter (Nonkwelo et al., 1996, Schaefer et al., 1995b), along with expression of the non-coding RNAs. Here, LAT is linked to Burkitt lymphoma.
