CC   -!- FUNCTION: Encapsidates the genome protecting it from nucleases
CC       (Probable). The encapsidated genomic RNA is termed the nucleocapsid
CC       (NC) and serves as template for transcription and replication
CC       (Probable). The nucleocapsid has a left-handed helical structure (By
CC       similarity). As a trimer, specifically binds and acts as a chaperone to
CC       unwind the panhandle structure formed by the viral RNA (vRNA) termini
CC       (By similarity). Involved in the transcription and replication
CC       initiation of vRNA by mediating primer annealing (By similarity). Plays
CC       a role in cap snatching by sequestering capped RNAs in P bodies for use
CC       by the viral RdRp during transcription initiation (By similarity).
CC       Substitutes for the cellular cap-binding complex (eIF4F) to
CC       preferentially facilitate the translation of capped mRNAs (By
CC       similarity). Initiates the translation by specifically binding to the
CC       cap and 40S ribosomal subunit (By similarity). Prevents the viral
CC       glycoprotein N (Gn) from autophagy-dependent breakdown maybe by
CC       blocking autophagosome formation (By similarity). Inhibits host
CC       EIF2AK2/PKR dimerization to prevent PKR-induced translational shutdown
CC       in cells and thus the activation of the antiviral state (By
CC       similarity). Also displays sequence-unspecific DNA endonuclease
CC       activity (By similarity). {ECO:0000250|UniProtKB:O36307,

CC   -!- SUBUNIT: Homotrimer (By similarity). Homomultimer (By similarity).
CC       Homomultimerizes and binds to viral genomic RNA to form the
CC       nucleocapsid (By similarity). Interacts with host MAP1LC3B; this
CC       interaction participates to the protection of Gn from virus-triggered
CC       autophagy (By similarity). Interacts with host SNAP29; this interaction
CC       participates to the protection of glycoprotein N from virus-triggered
CC       autophagy (By similarity). Interacts (via N-terminus) with host RPS19;
CC       this interaction probably mediates the loading of the 40S ribosomal
CC       subunit on viral capped mRNA during N-mediated translation initiation
CC       (By similarity). Interacts with the viral RdRp (By similarity).
CC       Interacts with host SUMO1 (via N-terminus) (By similarity). Interacts
CC       with host DAXX (By similarity). Interacts with the viral glycoprotein N
CC       (via C-terminus) (By similarity). Interacts with the viral glycoprotein
CC       C (via C-terminus) (By similarity). {ECO:0000250|UniProtKB:P05133,

CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250|UniProtKB:P05133}. Host
CC       cytoplasm, host perinuclear region {ECO:0000250|UniProtKB:P05133}. Host
CC       Golgi apparatus, host cis-Golgi network {ECO:0000250|UniProtKB:P05133}.
CC       Note=Internal protein of virus particle.
CC       {ECO:0000250|UniProtKB:P05133}.
CC   -!- DOMAIN: The N-terminus is required for chaperone activity and, in
CC       trimeric form, this region likely serves in high affinity vRNA
CC       panhandle recognition (By similarity). The N-terminus also contains a
CC       coiled coil region, which probably participates in but is insufficient
CC       to initiate N trimerization (By similarity). The YxxL motif is
CC       indispensable for the interaction with host MAP1LC3B (By similarity).
CC       The central region is involved in specific RNA-binding (By similarity).
CC       Has distinct cap- and RNA-binding sites so it can bind simultaneously
CC       both the vRNA and mRNA cap (By similarity).
CC       {ECO:0000250|UniProtKB:P05133, ECO:0000250|UniProtKB:Q89462}.
CC   -!- SIMILARITY: Belongs to the hantavirus nucleocapsid protein family.
