Virol. 90:1048-1061(2016). 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 (PubMed:15650206, PubMed:15254200, PubMed:21378500, PubMed:16971445, CC PubMed:25062117, PubMed:16775315). Involved in the transcription and CC replication initiation of vRNA by mediating primer annealing CC (PubMed:20164193). Plays a role in cap snatching by sequestering capped CC RNAs in P bodies for use by the viral RdRp during transcription CC initiation (PubMed:19047634). Substitutes for the cellular cap-binding CC complex (eIF4F) to preferentially facilitate the translation of capped CC mRNAs (PubMed:18971945, PubMed:25062117). Initiates the translation by CC specifically binding to the cap and 40S ribosomal subunit CC (PubMed:20844026, PubMed:20164193, PubMed:25062117). 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 (PubMed:27261891). {ECO:0000250|UniProtKB:O36307, CC ECO:0000250|UniProtKB:P05133, ECO:0000269|PubMed:15254200, CC ECO:0000269|PubMed:15650206, ECO:0000269|PubMed:16775315, CC ECO:0000269|PubMed:16971445, ECO:0000269|PubMed:18971945, CC ECO:0000269|PubMed:19047634, ECO:0000269|PubMed:20164193, CC ECO:0000269|PubMed:20844026, ECO:0000269|PubMed:21378500, CC ECO:0000269|PubMed:25062117, ECO:0000269|PubMed:27261891, ECO:0000305}.

Homomultimer (PubMed:26559827). Homomultimerizes and CC binds to viral genomic RNA to form the nucleocapsid (By similarity) CC (PubMed:26559827). Interacts with host MAP1LC3B; this interaction CC participates to the protection of Gn from virus-triggered autophagy. CC Interacts with host SNAP29; this interaction participates to the CC protection of glycoprotein N from virus-triggered autophagy (By CC similarity). Interacts (via N-terminus) with host RPS19; this CC interaction probably mediates the loading of the 40S ribosomal subunit CC on viral capped mRNA during N-mediated translation initiation CC (PubMed:20844026, PubMed:25062117). Interacts with the viral RdRp; this CC interaction is required for RdRp function (PubMed:24850733). Interacts CC with host SUMO1 (via N-terminus) (By similarity). Interacts with host CC DAXX (By similarity). Interacts with the viral glycoprotein N (via C- CC terminus) (By similarity). Interacts with the viral glycoprotein C (via CC C-terminus) (By similarity). {ECO:0000250|UniProtKB:P05133, CC ECO:0000250|UniProtKB:P27313, ECO:0000250|UniProtKB:Q88918, CC ECO:0000269|PubMed:15254200, ECO:0000269|PubMed:15650206, CC ECO:0000269|PubMed:20844026, ECO:0000269|PubMed:24850733, CC ECO:0000269|PubMed:25062117, ECO:0000269|PubMed:26559827}. 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 (PubMed:21378500). The N-terminus also contains a CC coiled coil region, which probably participates in but is insufficient CC to initiate N trimerization (PubMed:17222867). 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 (PubMed:20164193). CC {ECO:0000250|UniProtKB:P05133, ECO:0000269|PubMed:17222867, CC ECO:0000269|PubMed:20164193, ECO:0000269|PubMed:21378500}. CC -!- SIMILARITY: Belongs to the hantavirus nucleocapsid protein family.
