NSP15 is encoded by ORF1a/1ab and proteolytically released from the pp1a/1ab polyprotein.

NSP15 is encoded by ORF1a/1ab and proteolytically released from the pp1a/1ab polyprotein. This domain exhibits endoribonuclease activity designated EndoU, highly conserved in all known CoVs and is part of the replicase-transcriptase complex that plays important roles in virus replication and transcription [1, 2, 3]. NSP15 is a Uridylate-specific endoribonuclease that cleaves the 5'-polyuridines from negative-sense viral RNA, termed PUN RNA either upstream or downstream of uridylates, at GUU or GU to produce molecules with 2',3'-cyclic phosphate ends [2, 3]. PUN RNA is a CoV MDA5-dependent pathogen-associated molecular pattern (PAMP) [3].

NSP15, is a nidoviral RNA uridylate-specific endoribonuclease (NendoU) carrying C-terminal catalytic domain belonging to the EndoU family. The SARS-CoV-2 NendoU monomers assemble into a double-ring hexamer, generated by a dimer of trimers. The hexamer is stabilized by the interactions of N-terminal oligomerization domain.
