| - | + | [https://www.uniprot.org/uniprot/NCAP_SINV NCAP_SINV] Encapsidates the genome protecting it from nucleases (Probable). The encapsidated genomic RNA is termed the nucleocapsid (NC) and serves as template for transcription and replication (Probable). The nucleocapsid has a left-handed helical structure (By similarity). As a trimer, specifically binds and acts as a chaperone to unwind the panhandle structure formed by the viral RNA (vRNA) termini (PubMed:15650206, PubMed:15254200, PubMed:21378500, PubMed:16971445, PubMed:25062117, PubMed:16775315). Involved in the transcription and replication initiation of vRNA by mediating primer annealing (PubMed:20164193). Plays a role in cap snatching by sequestering capped RNAs in P bodies for use by the viral RdRp during transcription initiation (PubMed:19047634). Substitutes for the cellular cap-binding complex (eIF4F) to preferentially facilitate the translation of capped mRNAs (PubMed:18971945, PubMed:25062117). Initiates the translation by specifically binding to the cap and 40S ribosomal subunit (PubMed:20844026, PubMed:20164193, PubMed:25062117). Prevents the viral glycoprotein N (Gn) from autophagy-dependent breakdown maybe by blocking autophagosome formation (By similarity). Inhibits host EIF2AK2/PKR dimerization to prevent PKR-induced translational shutdown in cells and thus the activation of the antiviral state (By similarity). Also displays sequence-unspecific DNA endonuclease activity (PubMed:27261891).[UniProtKB:O36307][UniProtKB:P05133]<ref>PMID:15254200</ref> <ref>PMID:15650206</ref> <ref>PMID:16775315</ref> <ref>PMID:16971445</ref> <ref>PMID:18971945</ref> <ref>PMID:19047634</ref> <ref>PMID:20164193</ref> <ref>PMID:20844026</ref> <ref>PMID:21378500</ref> <ref>PMID:25062117</ref> <ref>PMID:27261891</ref> | |

Hantaviruses can cause hemorrhagic fever with a renal syndrome and hantavirus pulmonary syndrome when transmitted to humans. The nucleocapsid protein of hantaviruses encapsidates viral genomic RNA and associates with transcription and replication complexes. Both the amino and carboxy termini of the nucleocapsid protein had been predicted to form trimers prior to the formation of the ribonucleoprotein. Crystal structures of amino-terminal fragments of the nucleocapsid protein showed the formation of intramolecular antiparallel coiled coils, but not intermolecular trimers. Thus, the amino-terminal part of the nucleocapsid protein is probably insufficient to initiate the trimerization of the full-length molecule. | Hantaviruses can cause hemorrhagic fever with a renal syndrome and hantavirus pulmonary syndrome when transmitted to humans.
