چکیده انگلیسی
The vaccinia virus A43R open reading frame encodes a 168-amino acid protein with a predicted N-terminal signal sequence and a C-terminal transmembrane domain. Although A43R is conserved in all sequenced members of the orthopoxvirus genus, no non-orthopoxvirus homolog or functional motif was recognized. Biochemical and confocal microscopic studies indicated that A43 is expressed at late times following viral DNA synthesis and is a type-1 membrane protein with two N-linked oligosaccharide chains. A43 was present in Golgi and plasma membranes but only a trace amount was detected in sucrose gradient purified mature virions and none in CsCl gradient purified enveloped virions. Prevention of A43R expression had no effect on plaque size or virus replication in cell culture and little effect on virulence after mouse intranasal infection. Although the A43 mutant produced significantly smaller lesions in skin of mice than the control, the amounts of virus recovered from the lesions were similar.
