title: Sindbis virus nsP1 functions in negative-strand RNA synthesis.
abstract: A mutation at nucleotide 1101 of Sindbis virus ts11 nsP1 caused temperature-sensitive negative-strand synthesis and suppressed the 24R phenotype, which is caused by a mutation in nsP4. Nonstructural proteins synthesized and accumulated by ts11 at 40 degrees C did not cause the reactivation of negative-strand synthesis upon return to 30 degrees C and did not prevent the formation of new replication complexes at 30 degrees C.
