Anti-MeV Phosphoprotein Polyclonal Antibody|抗MeV磷蛋白多克隆抗体(靶标：麻疹病毒磷蛋白)

Phosphoprotein is a ~53 kDa protein. Essential cofactor of the RNA polymerase L that plays a central role in the transcription and replication by forming the polymerase complex with RNA polymerase L and recruiting L to the genomic N-RNA template for RNA synthesis. Also plays a central role in the encapsidation of nascent RNA chains by forming the encapsidation complex with the nucleocapsid protein N (N-P complex). Acts as a chaperone for newly synthesized free N protein, so-called N0, allowing encapsidation of nascent RNA chains during replication. The nucleoprotein protein N prevents excessive phosphorylation of P, which leads to down-regulation of viral transcription/ replication. Participates, together with N, in the formation of viral factories (viroplasms), which are large inclusions in the host cytoplasm where replication takes place.
