RT Journal Article SR Electronic(1) A1 Person, Stanley A1 Laquerre, Sylvie A1 Desai, Prashant A1 Hempel, JohnYR 1993 T1 Herpes simplex virus type 1 capsid protein, VP21, originates within the UL26 open reading frame JF Journal of General Virology, VO 74 IS 10 SP 2269 OP 2273 DO https://doi.org/10.1099/0022-1317-74-10-2269 PB Microbiology Society, SN 1465-2099, AB The goal of experiments reported here was to identify the genes that encode capsid proteins VP21 and VP24 of herpes simplex virus type 1 (HSV-1). Capsids were isolated from infected cells and the proteins were separated by SDS-PAGE. N-terminal amino acid sequence analysis of partial CNBr digestion products, and of intact VP21, showed that it is encoded within the UL26 open reading frame (ORF) of HSV-1 beginning with codon 248 and probably extending to the end of the ORF (codon 635). Similar analysis of digestion products confirmed that VP24 is specified by codons 1 to 247 at the 5′ end of the UL26 ORF. Each of the seven known capsid proteins has now been assigned to an ORF., UL https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-74-10-2269
