Function

RNA dependent RNA polymerase. Replicates genomic and antigenomic RNA by recognizing replications specific signals. The early replication complex formed by the polyprotein P123 and nsP4 synthesizes minus-strand RNAs.

Biological Context

Subcellular Location: Host cytoplasmic vesicle membrane (Peripheral membrane protein)

Product Specifications

Recombinant Chikungunya virus Non-structural protein 4 (nsP4), partial is a recombinant protein from Chikungunya virus (strain S27-African prototype) (CHIKV), expressed in E.coli, covering amino acids 2228-2474aa, with N-terminal 6xHis-tagged tag, molecular weight 31.1kDa, purity Greater than 90% as determined by SDS-PAGE..

Protein Biology

Function

RNA dependent RNA polymerase (By similarity). Replicates genomic and antigenomic RNA by recognizing replications specific signals. The early replication complex formed by the polyprotein P123 and nsP4 synthesizes minus-strand RNAs (By similarity). The late replication complex composed of fully processed nsP1-nsP4 is responsible for the production of genomic and subgenomic plus-strand RNAs (By similarity)

Subcellular Location

Host cytoplasmic vesicle membrane (Peripheral membrane protein)

Subunit

Interacts with RNA-directed RNA polymerase nsP4 (PubMed:22951312). Interacts with mRNA-capping enzyme nsP1 (PubMed:22951312). Interacts with KPNA1/karyopherin-alpha1; this interaction probably allows the active transport of protease nsP2 into the host nucleus (By similarity)
