FIG. 1.
EBV BSLF2/BMLF1 (SM/M) genes, transcripts, and protein products. The portion of the B95-8 genome that encodes the BSLF2/BMLF1 proteins is shown below a size scale. Transcription occurs in the leftward direction, generating two transcripts of 1.8 (SM) and 1.7 (M) kb in length. The phosphoproteins migrate at approximately 50 and 60 kDa in SDS-PAGE. The shaded portions of SM and M are identical; the hatched region of SM represents the extra N-terminal 41 amino acids encoded by BSLF2.
