CC -!- FUNCTION: Encapsidates the genome, protecting it from nucleases. The
CC encapsidated genomic RNA is termed the nucleocapsid (NC). Serves as
CC template for viral transcription and replication. The increased
CC presence of protein N in host cell does not seem to trigger the switch
CC from transcription to replication as observed in other negative strain
CC RNA viruses. Through the interaction with host IKBKE, strongly inhibits
CC the phosphorylation and nuclear translocation of host IRF3, a protein
CC involved in interferon activation pathway, leading to the inhibition of
CC interferon-beta and IRF3-dependent promoters activation. Encodes also a
CC functional 3'-5' exoribonuclease that degrades preferentially dsRNA
CC substrates and thereby participates in the suppression of interferon
CC induction. {ECO:0000255|HAMAP-Rule:MF_04085}.
CC -!- SUBUNIT: Homomultimerizes to form the nucleocapsid. Binds to viral
CC genomic RNA. Interacts with glycoprotein G2. Interacts with protein Z;
CC this interaction probably directs the encapsidated genome to budding
CC sites. Interacts with protein L; this interaction does not interfere
CC with Z-L interaction. Interacts with host IKBKE (via Protein kinase
CC domain); the interaction inhibits IKBKE kinase activity.
CC {ECO:0000255|HAMAP-Rule:MF_04085}.
CC -!- SUBCELLULAR LOCATION: Virion {ECO:0000255|HAMAP-Rule:MF_04085}. Host
CC cytoplasm {ECO:0000255|HAMAP-Rule:MF_04085}.
CC -!- DOMAIN: The N-terminal region is important for the cap-binding activity
CC while the C-terminal region contains the 3'-5' exoribonuclease
CC activity. A CCHE zinc binding site is present in the C-terminal region
CC and may thus contribute to the substrate binding and/or the specificity
CC of the exonuclease activity. {ECO:0000255|HAMAP-Rule:MF_04085}.
CC -!- SIMILARITY: Belongs to the arenaviridae nucleocapsid protein family.
CC {ECO:0000255|HAMAP-Rule:MF_04085}.
