The LMP1 gene is transcribed from a unique promoter in the latency types IIa and III.42,43 Although expression of the gene is limited to resting B cells for several days after infection,25 expression is later increased by EBNA2 protein.44 LMP1 is regarded as a oncoprotein and is required for the efficient transformation of B cells. The gene discussed is PDLIM7; the disease is infection.
